[antlr-interest] Lexical states and XQuery revisited

[howardckatz <howardk at fatdog.com>]

Has anybody implemented anything at all complicated using lexical 
states? I'm looking at the XQuery grammar, and it's heavily dependent 
on the use of lexical states, as is XPath 2.0. 

I tried implementing XQuery in antlr about a year ago and it was 
beyond me because of this issue. I ended up going to JavaCC, which 
handles lexical states quite easily. However I'd like to give antlr 
another try if anybody has any good pointers for me.

Thanks,
Howard
