XML Datetime and JSON datetime attributes differ

[konung]

This is not critical - I'll open an issue if it's really a bug top - is AMS XML, middle Roar XML, last - Roar-json a couple of things I noticed. Roar XML vs Roar JSON - date format gets changed. A bit unexpected Also with sorry meant AMS not Ares XML - with AMS xml attributes - are hyphented. I actually like the _ style. Also shouldn't it display attribute type by default? Are these by design?
