Remarks

This attribute is ignored unless the containing method is marked with the XdmFunctionAttributeXdmFunctionAttributeXdmFunctionAttribute, and the containing object is marked with XdmModuleAttributeXdmModuleAttributeXdmModuleAttribute.

The type specified by this attribute must be a subtype of the primitive base type of the XDM type represented by the CLR type of the argument or return value of the function annotated with this annotation. For example if a function has an argument with CLR type intIntegerint then its XDM type is xs:int, whose primitive base type is xs:integer. This means that the argument can be annotated with any subtype of xs:integer.

If an argument or return value has a CLR type that is a subtype of XPathItemXPathItemXPathItem (for example XPathNavigatorXPathNavigatorXPathNavigator) then the type that can be specified by this attribute must be representable by the argument.

If at runtime a value passed to an argument cannot be converted from the declared type to the CLR type then an ANDY1000 error is raised at runtime. Similarly if a value returned from a function cannot be converted to its declared type, or if a value returned is of a type annotated with XDM type information (for example XPathAtomicValueXPathAtomicValueXPathAtomicValue) and is not a subtype of the functions declared type then an ANDY1000 error is raised at runtime.
