[matrix] Problem regarding Malayalam implementation

[Emily M. Bender]

Hi Anila,

Those constraints on inflected and infl-satisfied look appropriate,
at first glance.

What is the rule that licenses the constituent that becomes the
daughter of the coordination phrase in the illicit parses?  Look at
the parse chart, get the edge that corresponds to that daughter,
and look at its local avm (from the pop up menu in the parse chart).
What is the value for INFLECTED on that node?

Emily
