Remarks

The XdmDocumentXdmDocumentXdmDocument is the preferred document type for documents used in an XQuery program, an XPath expression, or an XSL transformation.

The XdmDocumentXdmDocumentXdmDocument differs from XPathDocument XPathDocument XPathDocument in the following respects:

When the source XmlReader XmlReader XmlReader is a validating reader, XML Schema type information is exposed through the SchemaInfo SchemaInfo SchemaInfo property.
For elements with complex-only content (as defined by XML Schema), any white space text node children will be discarded.

The current XdmDocumentXdmDocumentXdmDocument implementation is currently unable to read external DTDs, which is required to determine which attributes are marked as ID or IDREFS. This is because the XmlReader XmlReader XmlReader class does not expose the types of attributes declared in a DTD. This has the effect that the fn:id and fn:idref functions may not work correctly.

Markup declarations specified directly in the internal subset are processed to determine the types of attributes.
