Excellent! Would that others would do the same!

N372 splits the two components of the XTM specification across two 
documents: The syntax specification itself is proposed as an annex to ISO 
13250, whereas the deserialization syntax is an annex to the SAM.

The original plan was to have both parts in one document (of which N328 is the current draft).

Lars Marius has pointed out that this is illogical and also means having to 
redo a lot of work. In addition, it leads us to repeating the mistake we 
made in the original 13250 of defining topic maps in terms of an 
interchange syntax rather than a data model. (ISO 13250 would stand as the 
primary definition of Topic Maps but would not include the data model, 
which N372 suggests should be in a separate standard.)

Hope this clarifies things.
