The Python PySchemaValidator is failing to validate an XML document if supplied as an XdmNode.

For example the following script:

    invalid_xml = "<?xml version='1.0'?><request><a/><!--comment--></request>"
    sch1 = "<xs:schema xmlns:xs='http://www.w3.org/2001/XMLSchema' elementFormDefault='qualified' attributeFormDefault='unqualified'><xs:element name='request'><xs:complexType><xs:sequence><xs:element name='a' type='xs:string'/><xs:element name='b' type='xs:string'/></xs:sequence><xs:assert test='count(child::node()) = 3'/></xs:complexType></xs:element></xs:schema>"
    input_ = saxonproc2.parse_xml(xml_text=invalid_xml)
    print(type(input_))
    val.set_source_node(input_)
    val.register_schema(xsd_text=sch1)
    val.validate()

Throws the exception:

saxoncee.PySaxonApiError: Source document not found. Line number: -1

The workaround is supply the XML document as a file using the file_name keyword argument.

This worked in SaxonC 12.4.2.
