The (Candidate) Requirements document for 1.1 asserts under the
discussion of RQ-6 that:

>Discussion on the June 19, 2003, telcon 
>established that in the 2e draft, all simple 
>types to which the length facet applies  have 
>lengths defined.

I have just noticed that this is not true.  QName and the related
NOTATION do not appear to have a reasonable length defined.  (Note
that "length" is supposed to apply to the value space.)  I do not
recall a phase 1 decision defining length for either of these two
datatypes, and the description of NOTATION in 1.1 currently asserts:

>The use of ·length·, ·minLength· and ·maxLength· 
>on NOTATION or datatypes ·derived· from NOTATION 
>is deprecated.  Future versions of this 
>specification may remove these facets for this 
>datatype.

QName has a similar deprecation.

We were in error closing out RQ-6.  Frankly, I don't see any reasonable
way to define a length for either; I think we should disallow the
three length facets for these two datatypes as warned in 1.0 2E.
