A couple of comments...

Section 2.3:

You explicitly exclude xml:lang, but don't mention xml:base here, though 
you mention above that xml:base attributes are excluded for 
xml:base-conformant applications.

I'm tending to think that it might be simpler to simply exlcude xml:base 
from consideration:  if an application is xml:base conformant then its 
effect is on the rest of the infoset as expected.  For applications that 
are not xml:base conformant, isn't the attribute meaningless 
anyway?  (Which suggests to me that documents that differ only in xml:base 
attributes convey the same information as far as such an application is 

Section 2.8:

It seems counter-intuitive to me that document that differ only in their 
comments are different in the sense you outline in section 1 -- to me, for 
most applications of XML, they would convey the same information.

Ah... I see you address this in section 3.  Hmmm... Now I'm beginning to 
wonder if a variable "cookbook recipe" like this is truly an 
_architectural_ finding (which comment should not be read as implying it is 
not useful).
