Any plans for Xerces to ever use Java 5 constructs?

[David M Williams]

Seeing @xerces.internal in a recent post, reminded
me, I've been meaning to ask ... 

Has there ever been any thought or plans to support
any of the Java 5 language constructs? 
Such as enums, generics? I'm not saying I need it
or even that it'd be nice to have ... I'm just curious
at this point. 

Thanks for any pointers to "plans" ... I
didn't see any at
