[antlr-interest] How to set a Token within the Filterrule (wa s 'Understanding $setType; how to use')

[mzukowski at bco.com]

A filter will filter tokens out of the stream going to the parser, so that's
not what you want.

Rename your filter rule to TAG, make it unprotected, set the
testLiterals=true option, and remove the OTITLE rule and instead make
<title> a literal.
