Fixed a code generation bug (exhibited in XmlSpec schema (xmlspec.xsd)) when the simple type enum for xlink:type attribute was not being generated.
Fixed a code generation bug whereby the wrong type name was referenced when the property name and type name were the same, and the XML schema did not have [Element Form Default="qualified"] set and the property type was reflecting an XSD union type (like the xml:lang attribute) (exhibited in 'W3C XMLSchema v1.xsd').
Fixes a code generation bug with certain XName fields (that are only referenced in the static constructor of a type) were not getting created.
Adds .NET Framework 4.7.2 target for the testing suite.
Release 3.4.2
