XmlPrime 2.0

• Complete support for XSL Transformations (XSLT) 2.0 has been added. See XsltXsltXslt and XsltSettingsXsltSettingsXsltSettings.
• MSBuild Tasks are now provided for invoking XQuery queries and XSL Transformations. See XmlPrime MSBuild Task Library for more information.
• Improved the AnyUriAnyUriAnyUri class. Added the AnyUri.GetComponentsAnyUri.GetComponentsAnyUri::GetComponents method to match Uri.GetComponentsUri.GetComponentsUri::GetComponents.
• Duplicate XML Declarations were being produced when serializing a query whose result is a document node.
• Added XdmDocumentWriterXdmDocumentWriterXdmDocumentWriter class to enable direct serialization to an XdmDocumentXdmDocumentXdmDocument.
• Fixed a bug in the handling of the second argument of MoveToFollowingMoveToFollowingMoveToFollowing of navigators over XdmDocumentXdmDocumentXdmDocument which resulted in incorrect results.
• Fixed a bug in generation of namespace prefixes which caused duplicate namespace declaration to be written.
• Fixed a bug with recursive functions which iterate over range expressions.

Breaking Changes:

• Moved the StaticContextSettings.TypeCheckingMode property to the XPathSettingsXPathSettingsXPathSettings and XQuerySettingsXQuerySettingsXQuerySettings classes, as this is not currently applicable to XSLT.
• Renamed the misspelt function XdmNavigator.UnparsedEntityPublicDd and XdmNavigator.UnparsedEntitySystemDd to UnparsedEntityPublicIdUnparsedEntityPublicIdUnparsedEntityPublicId and UnparsedEntityPublicIdUnparsedEntityPublicIdUnparsedEntityPublicId respectively.
• Removed the M:XmlPrime.Serialization.XdmWriter.Serialize(System.Xml.XmlReader,System.IO.TextWriter,XmlPrime.Serialization.XdmWriterSettings) method as it is redundant to WriteNodeWriteNodeWriteNode.
• Removed T:XmlPrime.DelegatingXmlReader as it was accidentally made public in the last release.

• XML version (1.0 or 1.1) can now be specified in the static context.
• Results can now be serialized as XML 1.1.
• Query plans can now be output as XML.
• Mathematical functions due to be included in the next version of XPath and XQuery Functions and Operators have been moved into the math namespace.
• Rules for determining the validity of NCNames and QNames have been updated to reflect changes introduced in the 5th edition of XML 1.0.
• The types of external parameters can be specified via the static context.
• Improved efficiency of variables which are only evaluated once.
• Improved performance of user defined functions.
• Improved performance of functions which recurse on a subsequence of one of their arguments.
• Small for loops will be unrolled.
• Prevented optimizer from optimizing away runtime errors in some circumstances.
• Added handling for MIME types in the DocumentSet. This is required for correct behaviour of the XSLT document function.
• Introduced a new optimization level (OptimizationLevel.Specialization. This enables potentially expensive function specialization. This can be selected using -O4 with the command line tool.
• In some circumstances, namespace declarations could be erroneously omitted.
• Fixed nested XML Schema validation.
• Fixed output of empty XHTML elements during serialization.
• Many small fixes.

Breaking changes

• The CreateCreateCreate methods no longer take an XmlNameTableXmlNameTableXmlNameTable argument.
• XsltWhitespaceSettings has been renamed to InputSettingsInputSettingsInputSettings and now also includes input type annotations.
• ResourceResourceResource now returns ResolvedResourceResolvedResourceResolvedResource. Previously, it returned a StreamStreamStream.
• The Resolve method of IDocumentResolverIDocumentResolverIDocumentResolver has been replaced with ResolveDocumentResolveDocumentResolveDocument.
• The Resolve method of ICollectionResolverICollectionResolverICollectionResolver has been replaced with ResolveCollectionResolveCollectionResolveCollection.
• The Resolve method of IResourceResolverIResourceResolverIResourceResolver has been replaced with ResolveResourceResolveResourceResolveResource.
• The DefaultType property of IDocumentTypeResolverIDocumentTypeResolverIDocumentTypeResolver has been replaced with DefaultDocumentTypeDefaultDocumentTypeDefaultDocumentType.
• The Resolve method of IDocumentTypeResolverIDocumentTypeResolverIDocumentTypeResolver has been replaced with ResolveDocumentTypeResolveDocumentTypeResolveDocumentType.
• The DefaultType property of ICollectionTypeResolverICollectionTypeResolverICollectionTypeResolver has been replaced with DefaultCollectionTypeDefaultCollectionTypeDefaultCollectionType.
• The Resolve method of ICollectionTypeResolverICollectionTypeResolverICollectionTypeResolver has been replaced with ResolveCollectionTypeResolveCollectionTypeResolveCollectionType.

• Modules of functions can now be written in .NET and used in XQuery programs and XPath expressions.
• Intermediate (constructed) nodes are now serialized directly into XdmDocumentXdmDocumentXdmDocument instances, rather than building temporary trees. This should lead to improved performance of queries performing further processing on constructed nodes.
• Some more improvements to join analysis - left outer joins and group-by expressions are spotted (and hence optimized) more often.
• typeswitch expressions are now more efficient when the argument is a single item.
• ToStringToStringToString now returns the value cast to a string.
• Many small fixes.

Breaking changes

• XmlPrime.XPathLibraryCollection has been replaced with LibrarySetLibrarySetLibrarySet.
• XmlPrime.XPathFunctionCollection has been replaced with XdmModuleXdmModuleXdmModule.
• LocationHintCollectionLocationHintCollectionLocationHintCollection now stores location hints as AnyUriAnyUriAnyUri values rather than stringStringString values.
• CollationResolverCollationResolverCollationResolver now takes an ICollationResolverICollationResolverICollationResolver instead of CollationResolverCollationResolverCollationResolver. CollationResolverCollationResolverCollationResolver still exists and implements ICollationResolverICollationResolverICollationResolver, so this change should have minimal impact.

• The XmlPrime DLL can now be precompiled with ngen. Previously ngen would crash.
• Improved unboxed evaluation, especially for aggregate functions.
• Many small performance improvements.
• Internal changes in preparation for compiling queries to dynamic methods

• Queries can now be evaluated directly to a serializer, avoiding building an intermediate representation.
• Push-based evaluation has been implemented for all expressions, and is used for all expressions that are determined to be strict.
• Added the (# xp:eager #) pragma to force eager evaluation.
• import schema now ignores location hints if the namespace is already statically available.
• Imported schemas that fail to compile are no longer added to the available schema set.
• Fixed an exception when evaluating treat as empty-sequence() in some circumstances, and improved optimization of type constraints.
• Corrected behaviour of MoveToIdMoveToIdMoveToId for constructed nodes.
• Updated liveness analysis to fix problems when using partially evaluated lazy variables in join operations.
• Avoided distinct-doc-order for unions such as (@*|node()).
• Minor improvements to error messages.
• Many small performance improvements.

• Completely new serialization implementation.
  • Serialization interface now much closer to XmlWriterXmlWriterXmlWriter. There are some breaking API changes in the XmlPrime.SerializationXmlPrime.SerializationXmlPrime.Serialization namespace.
  • A new serialization method has been added which allows for serialization of Canonical XML 1.0.
  • XmlWriterXmlWriterXmlWriter instances can be created with the full set of serialization settings.
  • Some new serialization parameters have been added.
• XmlPrime now only requires .NET Framework 2.0, rather than 3.5.
• Added XmlPrime extension methods for .NET Framework 3.5 to give a simple way of executing XPath 2.0 expressions.
• Added some more constructors to XdmDocumentXdmDocumentXdmDocument, to match XPathDocumentXPathDocumentXPathDocument.
• Removed IXPathNavigableIXPathNavigableIXPathNavigable overloads for methods taking XPathItemXPathItemXPathItem, as this was causing calls with XPathNavigatorXPathNavigatorXPathNavigator to be ambiguous.
• Reverse axes were previously being cached and reversed. This is now skipped if the results are not needed in document order - eg. for /ancestor::*[1]
• Improved optimization of fn:data applied to constructed nodes.
• Conformance to latest errata regarding in-scope schema types from modules.
• Bug fixes:
  • XQuery parsing changed to reflect erratum regarding the leading-lone-slash constraint.
  • The order comparison of navigators over XdmDocumentXdmDocumentXdmDocument instances was incorrect for namespace nodes.
  • The fn:base-uri, fn:data and fn:node-name functions behaved incorrectly for namespace node arguments.
  • The parsing of URI ports was incorrect in AnyUriAnyUriAnyUri.
  • The UserInfoUserInfoUserInfo property was truncating the first character
  • Empty document nodes were incorrectly causing spaces to be inserted between sequences of atomic values when constructing an element's content
  • XPathNavigatorXPathNavigatorXPathNavigator instances were sometimes not being cloned when evaluating a query to a single node, leading to the returned navigator pointing to the wrong node.
  • Fixed some places where the static types of expressions were not being correctly updated during optimization, causing a NotSupportedExceptionNotSupportedExceptionNotSupportedException or ArgumentNullExceptionArgumentNullExceptionArgumentNullException at runtime.
  • In some cases function specialization was causing fn:subsequence to throw a NotSupportedExceptionNotSupportedExceptionNotSupportedException at runtime.
  • The optimized form of fn:sum($x to $y) was producing xs:decimal values instead of xs:integer values.
  • fn:distinct-values was missing an evaluator to produce XPathItemXPathItemXPathItem for upstream functions, leading to a NotSupportedExceptionNotSupportedExceptionNotSupportedException at runtime.
  • The in-scope namespaces of a constructed element did not include the empty prefix in some situations.
  • The fn:element-with-id function gave incorrect results for schema-defined union types including xs:ID.

• Set default type checking mode to optimistic, as per documentation.
• Fixed compatibility with XmlDocumentXmlDocumentXmlDocument
  • Fixed NullReferenceExceptionNullReferenceExceptionNullReferenceException when using fn:data() caused by XmlDocumentXmlDocumentXmlDocument returning an IXmlSchemaInfoIXmlSchemaInfoIXmlSchemaInfo instance with null SchemaTypeSchemaTypeSchemaType.
  • Fixed infinite loop caused by an XPathNodeIteratorXPathNodeIteratorXPathNodeIterator over XmlDocumentXmlDocumentXmlDocuments not consistantly returning false after the end of the node set.
  • Fixed the XQuery version declaration for cultures where '.' is not the decimal point.
  • Fixed normalization rules of general comparisons as per erratum XQ.E18.
• For increased performance, the command line tool now runs in x86 mode by default.

• First full release.
