...regarding how to handle Keywords That Look Like Identifiers...

something like (haven't actually run it through the tool):

class ErsinErLexer extends Lexer;

options { testLiterals=false; }

tokens { ID_AND="and"; ID_OR="or"; }

OID options{ testLiterals=true; } : NUMERICOID | DESCR;
protected DESCR: ALPHA ( ALPHA | DIGIT | '-' )*;
protected ALPHA: 'A'..'Z' | 'a'..'z';

NUMERICOID : ...whatever...

...other lexer rules, but *not* ID_AND | ID_OR...
