You're right, writing a variant for mrs::get-mrs-string() wasn't difficult at
all. I added a function mrs::get-mrs-xml-string() in the attached patch. I'm not
sure whether other formats such as DMRS or RMRS are as simple to realize, but I
don't care for the moment. Is anyone else interested in such a function?

I also modified the redwoods script to allow you to specify which semantic hook
you want to use with the command-line option --sem <value>. It's by default set
to the value "simple" (i.e. mrs::get-mrs-string()), thus not changing the
current behaviour of the redwoods script, but you can also specify "indexed",
"resolved", "xml" or "nil".

This brings me to two similar issues:

1) Can I process a parsebank (i.e. with all readings) just in order to
reconstruct the semantics?

2) How do I thin a parsebank to the reading with the highest score as determined
by the maxent reading selection model?

Cheers,

Peter
