Which reminds me that we somewhere have to define PSIs for

 "XTM", the notation
 "CTM", the notation

Once we have that, yes, we *should* have predefined

  xtm isa topicmap-notation
  - "XTM"

Once there, we could also consider staying within the TM paradigm:

  some-other-file isa ctm:stream   ~ file:myfile.ctm

This reads in the CTM file and merges it with the currently processed

  something isa ctm:stream
    ctm:notation xtm
    ~ http://some.where/file.xtm

Or if that is generated on the fly:

  mystaff isa ctm:stream
    ctm:notation astma
    ctm:command : "cat ... | ... |"

[ As always: Not sure about the current CTM syntax. :]
