[topicmapmail] Data Model question : Identifying subjects

[Peter P. Jones]

Erm...
Does that mean PSI URIs should always be encapsulated in a 
resourceRef element then?
(Since it was supposed to be inherent in the idea of PSI that they be 
indicate the subject unambiguously - and hence, on past thinking, the 
mere URI would substitute as an adequate proxy.)

That is, I believe what the text of the draft standard you quoted 
says there seems to indicate that 'subject indicating' and 'published 
subject identifying' are two different things and need to be 
indicated in the syntax as such.

No doubt this idea went the rounds at OASIS PSI committee meets. 
What was the debate's outcome?
