Hi,

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.

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.
