I agree with what David says here which is why I wrote the piece as I did:
Getting people to agree on a profile would be impossible (and I certainly recognized that when I chatted with some of
the WS-I schema wg folks).  So I wrote this article getting a profile from what people are actually using in their
schemas.  A sort of vote based on the schemas rather than a vote based on a show of hands.

I wonder why they do not base it on a comprehensive spec, such as ISO/IEC 11404 "Language Independent Datatypes".

Last year, the W3C organized a workshop, hosted at Oracle, addressing this issue (among others).  

The chairs' summary of the workshop is at 

It contains pointers to the agenda, and the minutes of both days of the workshop (including pictures). 
Most major software vendors attended this meeting.  The original subject of the workshop was raised by WSI:  "what to do
about XML Schema Profiling."

I think the minutes and the chairs' summaries give a fair indication of industry consensus, at least in May 2005.  I
don't know that much has changed since that point.  My personal take-away from the workshop was that many participants
thought a profile might be useful, but gaining consensus on what it might actually be seemed a daunting task.  (N.B. XML
Schema itself is an attempt to "profile" what most people want.)

The W3C response was to create a "databinding WG" in the Web Services Activity that is addressing these concerns.  They
do their work in public space, and I know they are eager for input from concerned folks, so I strongly recommend that
you take a look at their accomplishments so far:

 <http://www.w3.org/2002/ws/databinding/> http://www.w3.org/2002/ws/databinding/ 

This group really is concerned with interoperability of XML languages defined in XML Schema. 

Hope this helps.
