Subreadings in Constraint Grammar

Current situation

Typical input with sub-readings:

^foobar/foo+bar/fubar/flue+barge$

Right now, only the last sub-reading is used, in the above example, vislcg3 treats it as if it were

^foobar/bar/fubar/barge$

This works great for compounds where the stuff before the + is mostly inconsequential, while for other multiword expressions it is not so good... (Also, mapping tags are only put on the last sub-reading now.)

Wait can't we just split on the + with pretransfer before sending this to cg-proc?

No, because we first have to disambiguate between eg. ^foobar/foo+bar/fubar/flue+barge$ (what would that even look like if split? wouldn't work)

What we need

• We may need to refer to an earlier sub-reading in order to disambiguate
• We may want to put a mapping tag on an earlier sub-reading
