Yes, this is one of the requirements. It is not directly reflected in
the use cases (it contains some use cases where the item identifier
should be omitted and only a subject identifier should be used), but
this requirement was noted in the CTM requirements presentation in

I think, this should be relaxed. In AsTMa= this is already relaxed and
this should go into CTM.
Your example above would be valid in AsTMa=

     %prefix isbn i'urn:isbn:
     %prefix bibtex i'http://psi.something.here.com/

     isbn:0201749602 is-a bibtex:book
     tn: XML Topic Maps....
