Okay, this sounds like feature, which will help us build
a smart auto-completion list of next token ...  Right?

Very nice.

I do not catch ... Widget Java only?
   What will do C++ developers :-)

Actually we think not about GUI widget, but about
Feature of ANTLR to produce XML file from any grammar



We add into that .g   or into  antlr -switch

   > antlr  putput=xml  cpp.g

Will produce   cpp.g.xml (or sql.g.xml,  php.g.xml )

Which will contain language from .g expressed in XML format...
And may be reverse task XML to .g

Strange task?   :)   I know ...
