Hi Kelly,

Not really.
In fact, I've raised the issue again exactly because of the xml:id 
recommendation.

Fact is, I don't necessarily want to type xml:id all over the place, so 
having an id available
is highly desirable. 

As I recall, the rationale for leaving it out was kind of flimsy.  I 
believe the thinking was that 
the host document format might want to be in control of the naming 
convention for IDs 
throughout the document.

I think xml:id breaks that.

The other possibility was that the above might be needed to ensure that 
our declaration
of an id attribute didn't conflict with declarations needed by the host 
language if they
were trying to control ID-ness uniformly in some way.  However, this seems 
to confuse
the notion of having more than one possible ID attribute with actually 
declaring more than
one ID attribute, only the latter of which is non-valid.

And again, xml:id itself provides the possibility but not the reality of a 
second ID attribute.

Finally, notwithstanding the problems, it still doesn't seem very 
compelling compared to
not having an id attribute automatically available in the content model, 
esp. since we declare
so many IDREFs in the schema.

Does leaving this out have something to do with the xml:id Recommendation?
