[antlr-interest] sub-tree tree parsing

[Sohail Somani]

Hi,

I've been out of ANTLR for a little while but I seem to recall that
sub-tree tree parsing was going to be made possible. That is, given a
tree grammar, you could write a parser that would only need to
understand a part of it. This was in contrast to replicating the whole
grammar in each tree parser.

You could call it a "rule-based" tree parser.

Did this ever occur or did I dream it?
