Re: traversal attributes are NMTOKEN instead of NCNAME in the XML Schema

Norm,

Thank you for the correction. I am personally quite happy with the 
acknowledgement.

I should note that there has been some progress in the way XBRL uses XLink 
and the XML Schema for XLink. In order to facilitate interoperability with 
the CIQ group, we have modified our schema to include only those objects 
that can be absolutely justified by the text of the XLink specification. 
Previously, some objects (such as attribute groups) that appeared logical 
had been included. Hugh Wallis can provide the details of our discussions 
with CIQ and the changes made.

However, I think that the publication of a normative XML Schema would be 
the best path towards interoperability for XBRL, CIQ, SVG, and other 
groups wishing to use XLink.

Thanks again,

Apologies for the long delay in replying.

/ david.k.vun.kannon@us.pwc.com was heard to say:
| The non-normative XML Schema for XLink 1.1 mistakenly uses NMTOKEN as 
the
| restriction base for the types for the traversal attributes label, from, 
and to.
| These should be based on NCNAME, as stated in the text of the 
specification,
| section 5.7 (
http://www.w3.org/TR/2006/CR-xlink11-20060328/#traversal-atts).
| If you refer back to the XBRL schemas that were provided earlier in the 
1.1
| process, you can confirm that they use NCNAME, not NMTOKEN.

Fixed, thank you.

| Speaking as a private individual (not for the XBRL consortium or my 
company) I
| believe that XBRL is the largest use of XLink in the world. The chief 
avenues of
| extensibility provided by XBRL are new schemas, new XLink roles and arc 
roles,
| and new XLink linkbases. The XBRL consortium of more than 400 
organizations
| worldwide has recently opened a Link Role Registry to support reuse and
| interoperability of roles and arc roles. It would be appropriate if the 
donation
| of the XML Schemas for XLink, which first appeared in XBRL 2.0 (2001) 
was noted
| in the 1.1 document.

I added the following note to the end of the appendix that contains
the schema:

<p>Note: The Working Group acknowledges the work of the
<a href="http://www.xbrl.org/">XBRL Consortium</a>
in producing a W3C XML Schema for XLink 1.0, which was useful input
into the design of the schema document for XLink 1.1.</p>

Please let us know if this response is satisfactory.

                                        Be seeing you,
                                          norm
