[antlr-interest] Dynamic tokens

Hello everyone,

Consider the following grammar:

expr: IF element value THEN;

element: 'bla1 bla2' | 'xyz';
value: 'abc';


So  "IF bla1 bla2 abc THEN" would be a correct expression.
Nothing special, but this is static. I'd like to add elements and values 
during runtime.

What I mean is, that all elements and values known so far are stored in a 
Set instead of being hardcoded in the grammar.
And elements and values can be composed out of more than one word.

Is this possible?

Thank you!

Matthias
