           Summary: (re)move primitive (and derived) simple type defns from
           Product: XML Schema
           Version: 1.1
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P2
         Component: XSD Part 2: Datatypes

Proposition:  Including the simple type definitions for the primitive builtin 
datatypes in the schema document for schema documents is neither necessary nor 

As it stands many schema validators reject the schema document at 
http://www.w3.org/2001/XMLSchema.xsd because of these definitions, and they 
aren't needed to fulfil the primary purpose of the SDForSDs, namely to 
constrain the structure of schema documents.

In 2e we attempted to patch around the ways in which the SDForSDs violated our 
own constraints on SDs, but the result is arguably imperfect, and certainly 
doesn't contribute to the simplicity of the spec.

We could just remove them altogether, or put them in a separate section of the 
REC and/or a separate schema document on the Web.

The simple type definitions for the built-in derived datatypes are also not 
necessary -- should we (re)move them also?

One note of caution -- we have published URIs of the form 
http://www.w3.org/2001/XMLSchema#string and 
and the SDForSD contains anchors with those names.  Some people might suppose 
that those two things are connected, but it's not clear to me that in fact they 
are. . .
