Here everything looks file. I followed one link in that page that led me to this one: http://docs.codehaus.org/display/GEOTOOLS/TXT+Language+Analysis I have a few observations there (more like questions, it's not like I'm asking to address any of these): - the like filter still asks for a literal pattern. Why so, can't one have an expression that builds the pattern instead? Something like: att1 like (att2 + '%') Anyways, just a minor detail. - the values in the IN predicate, can they be expressions? > To see how the new parser work I recommend the unit test included in > > http://svn.geotools.org/trunk/modules/library/cql/src/test/java/org/geotools/filter/text/txt/TXTTest.java > > and the user documentation > > http://docs.codehaus.org/display/GEOTDOC/03+TXT+Examples > > You can find a lot of examples in the package > > cql/src/test/java/org.geotools.filter.text.txt > > The details about the new TXT grammar is in the following link: > > http://docs.codehaus.org/display/GEOTOOLS/TXT+Parser+Design > > Note that in the proposal, I add a release column, but it is only an idea > (maybe this is a PMC work?).

Looks fine to me for now, although of course it delays the usability of TXT for GeoServer by 6 months. I guess we're always free to do a backport later no? Ah, +1 for the proposal.
