Fix problems with SIRI 1.0 to 1.3 mapping

Enums were seen as primitive types that don't need conversion. However the siri-standard contains some enum's itself, not converting those resulted in exceptions effectively killing the application for use with a SIRI 1.0 endpoint
Actions made:

Create tests using SIRI 1.0 xml snippets
Only see enums as primitive when not part of the SIRI package
Convert enums using reflection and enum name
What's up with these unused variables?
