[antlr-interest] Explicit whitespace handling in W3C grammars

[Andreas Ravnestad]

In several of the grammars specified by the W3C, there are productions
that require "explicit whitespace handling" [1].

Consider this example:
A : B C;

With explicit whitespace handling, there can NOT be whitespace between
B and C in this production.

How can this be implemented with Antlr?
