Philippe and I have been carrying on a correspondence with Jonathan Marsh, WSDL WG chair, on the WS CG email list [1].  They are okay with us carrying forward with this work.

In Jonathan's most recent response [2] he requests that we consider adding a canonical form definition such as was recently added to WSDL 2.0 [3] to our WSDL 1.1 Element Identifiers material.  I have included the referenced section below for easy reference:

C.2 Canonical Form for WSDL 2.0 Component Designators

The IRI-references described above MAY be used as WSDL 2.0 component designators. For ease of comparison, the fragment identifier of WSDL 2.0 component designators SHOULD conform to the following canonicalization rules:

         The fragment identifier consists of a sequence zero or more xmlns() pointer parts followed by exactly one wsdl.*() pointer part. <http://dev.w3.org/cvsweb/~checkout~/2002/ws/desc/wsdl20/wsdl20.html?content-type=text/html;%20charset=utf-8#CanonFragId-1900002-summary#CanonFragId-1900002-summary>

         Each xmlns() pointer part that appears in the fragment identifier defines a namespace that is referenced by the wsdl.*() pointer part. <http://dev.w3.org/cvsweb/~checkout~/2002/ws/desc/wsdl20/wsdl20.html?content-type=text/html;%20charset=utf-8#CanonFragId-1900003-summary#CanonFragId-1900003-summary>

         Each xmlns() pointer part defines a unique namespace. <http://dev.w3.org/cvsweb/~checkout~/2002/ws/desc/wsdl20/wsdl20.html?content-type=text/html;%20charset=utf-8#CanonFragId-1900004-summary#CanonFragId-1900004-summary>

         The xmlns() pointer parts define namespaces in the same order as they are referenced in the wsdl.*() pointer part. <http://dev.w3.org/cvsweb/~checkout~/2002/ws/desc/wsdl20/wsdl20.html?content-type=text/html;%20charset=utf-8#CanonFragId-1900005-summary#CanonFragId-1900005-summary>

         The namespace prefixes defined by the xmlns() pointer parts are named ns1 , ns2 , etc., in the order of their appearance. <http://dev.w3.org/cvsweb/~checkout~/2002/ws/desc/wsdl20/wsdl20.html?content-type=text/html;%20charset=utf-8#CanonFragId-1900006-summary#CanonFragId-1900006-summary>

         The fragment identifier contains no optional whitespace. <http://dev.w3.org/cvsweb/~checkout~/2002/ws/desc/wsdl20/wsdl20.html?content-type=text/html;%20charset=utf-8#CanonFragId-1900007-summary#CanonFragId-1900007-summary>
