[matrix] prpstn_m_rel and mrs2rmrs

[Anette Frank]

Hi Dan, Ann (and others),
following Dan's announcement at the Delph-In meeting, that the standard for
coding of messages will soon be (or did already?) change, we would like to
make this adjustment also to our German RMRS bank before releasing it.
Before doing this, though, we would like to clarify the following issues:

-  To be sure: we assume that for the RMRS, the new representation 
should look
    like this:    (Although I *am* on the Matrix mailing list, I haven't 
seen any
   discussion of this - nor is there one obviously present in the Archive)

   prpstn_m_rel
   LBL h1
   ARG0 e1    (index/variable of the verb)
   MARG h2  

- At present, the conversion from (HPSG-produced) MRS to RMRS falsely 
converts
  the (current) MARG of message relations to ARG0. That is, for the new 
representation,
  we will have to   correct these conversion scripts, to avoid 
confusion/conflicts.
  As far as I can see, MARG should be allowed as a name for rargs in the 
RMRS DTD,
  so there shouldn't be a problem having MARG in the RMRS.
 
So, can we safely assume that these steps will be taken, and change our 
structures to
the new standard?

Regards,
  Anette and Kathrin
