Well. XTM 1.0 does not specify what can be reified. It hints that  
this is only topic characteristics, but that's clearly not what was  
actually intended, and even if it was it would be at odds with what  
core.xtm defines PSIs for.

In any case, you are referring to the state of Topic Maps  
standardization as it was in late 2000. Today what can and cannot be  
reified is defined by TMDM.

I don't think I want to enter into a discussion about whether we can  
call this formal semantics or not.
