This is an archived snapshot of W3C's public bugzilla bug tracker, decommissioned in April 2019. Please see the home page for more details.
I'm happy to see that the term "ur-type" has be superseded by "anyType" in XML Schema 1.1. Please make the corresponding replacement of "simple ur-type" with "anySimpleType".
A wording proposal to change occurrences of 'the simple ur-type definition' to 'xs:anySimpleType', and reformulate the definition of the term accordingly, has been prepared and is at http://www.w3.org/XML/Group/2004/06/xmlschema-1/structures.urtype.200611.html (member-only link) awaiting review by the WG.
The proposal mentioned in comment #1 was adopted by the working group on today's call. With that, we believe this issue to have been resolved, and I'm setting the status of the record to say that. Xan, thank you very much for the comment. When we next publish a working draft of the document, we hope that you will review the text of the document and confirm that the issue has been resolved to your satisfaction. (I'd attach a copy to the bug but it's kind of big and I don't want to saddle Bugzilla with a lot of copies of the XSD spec in varying states of revision.) If at that time you are happy with the resolution, please signal so by changing the status of this issue to CLOSED; otherwise, please let us know what's wrong and change it to REOPENED. If we don't hear from you within two weeks or so of publishing the next working draft, we will assume that you are satisfied. (In a perfect world, I'll remember to update this bug report or send you offline email to signal the availability of the text, but I don't want to promise that.)
