[antlr-interest] Error with date

[Jan van der Ven]

Ok, I solved it, but got another problem in return.
The parser matched the Feb/2003 to ID2
ID2 : ('a'..'z' |'A'..'Z' |'_' ) ('a'..'z' |'A'..'Z' |'_' |'0'..'9' | 
':' | '#' | '.' | '-' | ' ' | '/' )* ;
And if I remove the / from this definition, my timestamp is parsed 
correctly.
But not all my ID's.
I have several sort of ID's: some allow all characters, and some are 
more strict.
How would that be done?

Kind regards,

Jan
