This may have been discussed, but from what I have seen, xs:unions in 
general are badly supported by binding tools.  Hence this issue refers to a 
particular case of the more general xs:union issue.

I would hope that this situation would improve in future!

I'm not in a position to know what the criteria for a basic or advanced 
feature are. From my experience though, un-extensible enumerated types is 
one of the nastier versioning traps that XSD allows people to fall into (and 
they do), and for that reason it would be appealing to not have it too
