Characterisation is (unless something has recently broken) supported in 
both LKB and PET. Instructions below:

- ensure type 'relation' has attributes
  CFROM *top*
  CTO *top*

- set lkb::*characterize-p* to T
- ensure mrs::*initial-semantics-path* and mrs::*psoa-liszt-path* are 
set correctly (eg. see MRS documentation).
- (optionally) add CFROM/CTO to *ignored-sem-features*
- to see RMRS-XML set mrs::*rmrs-xml-output-p* to T

- set mrs-cfrom-path/mrs-cto-path in PET config file. Eg.
    mrs-cfrom-path := "SYNSEM.LOCAL.CONT.RELS.LIST.CFROM".
    mrs-cto-path   := "SYNSEM.LOCAL.CONT.RELS.LIST.CTO".
- to see RMRS-XML use the "-mrs=xml" option when calling cheap

Does this answer your question?
