Notes

The continuative aspect in Lakota is expressed via verbal enclitics. It is generally analyzed and written as a separate word, although some speakers treat it as a suffix. 

EB> I'm still puzzled about what you mean by "speakers treat it as".
Do you mean linguists?  Or is there something different in the way
those speakers pronounce the phrases?

We took a similar approach to the concept of hypothetical articles, providing a "hyp_q_rel" on those.

EB> Fair enough as a placeholder.  To really know how to model this,
I think we'd need a better idea of what these really mean.

We opted against forcing the bare-np to fire by specifying OPT + on the SPR because that would licence pronouns with SPR items.

EB> Actually, no.  The spec-head rule should check for compatibility
with [OPT -]. So [OPT +] really means "bare-np only".

In order to model the impersonal verbs, we needed to create a new verb type impersonal-verb-lex as well as the phrasal type impersonal-vp-phrase to license the structure. It was also necessary to constrain the LIGHT feature on this phrasal type in order to block the parser from an infinite loop.

EB> Why do you need this rule? Why can't the impersonal verbs function
directly as VPs?

We did this by constraining the KEYREL of the argument to noun-relation. 

EB> This is effectively restricting the daughter to being a
constituent consisting of a single word I think.  Can you get Adj + N
combinations in that position?

We also needed to change the top section to the following, as the suggestion to add (setf *variable-type-mapping* :semi) to lkb/mrsglobals.mrs appeared to have no effect:

e <> e
x <> x
i <> i
h <> h
p <> p
* >> u
semarg << u

EB> This was not the final solution.  You'll want to back out this
change and figure out how to make the *variable-type-mapping* solution
work --- the key is probably where it goes in mrsglobals.lsp.

In fact, translation wasn't working for me with the grammar you
submitted until I changed the semi back and uncommented the
*variable-type-mapping* line in mrsglobals.lsp.
