Description Sandy Gao 2005-09-09 03:06:19 UTC 
The Datatypes rec and the Schema for Datatypes do not allow the 
value "extension" for the final attribute of a simpleType.

However, section 3.4.6 of the Structures rec (under Derivation Valid 
(Extension)) says:

2 If the {base type definition} is a simple type definition, then all of the 
following must be true: 

2.1 The {content type} must be the same simple type definition. 
2.2 The {final} of the {base type definition} must not contain extension. 
It seems that 2.2 will always be true. Is this an oversight?

Comment 1 Sandy Gao 2005-09-09 03:07:06 UTC 
See:
http://lists.w3.org/Archives/Public/www-xml-schema-comments/2001OctDec/0068.html

and
http://lists.w3.org/Archives/Public/www-xml-schema-comments/2001OctDec/0069.html

Resolution:
Resolved at the March 8 telecon to class R-84 as clarification with erratum and 
change the Structures spec to agree with Datatypes as regards final='extension' 
on simple types.
Comment 2 Sandy Gao 2005-09-28 15:15:15 UTC 
Discussed at 2005-09-28 F2F meeting.

RESOLVED: Change the component of 2074 to Datatypes, remain as needs drafting, 
reassign to cmsmcq@w3.org
[11:14] ht: ... record a new resolution so that it is a direction to  bring 1.0 
datatypes in to line with the change agreed for 1.1, i.e. that {final} may 
include 'extension', and relevant comments about its use.

http://www.w3.org/Bugs/Public/show_bug.cgi?id=2234 is related, currently
(2005-11-03) comes to the wrong conclusion
Comment 4 Henry S. Thompson 2005-11-09 16:01:47 UTC 
http://www.w3.org/Bugs/Public/show_bug.cgi?id=2438 is the 1.1 fix for this problem
