Hi Jonathan/WSDL-WG,

This is a personal response. I hope that the WG can address this next week and send you an official response.

The differences are actually quite simple. XLink 1.0 uses almost exactly the same text as IRI Section 3.1 Step 2. It omits Step 1.

Step 1 consists of three things.

1a. covers when you transcribe an IRI into a digital form from a non-digital form (e.g. when you type in the IRI you wrote down on a napkin earlier). This can't apply to WSDL, of course, unless the WSDL starts to be printed on the sides of buses or the backs of envelopes :-).

1b. covers conversion from a "legacy" (non-Unicode) encoding to a Unicode encoding and requires normalizing the text using Unicode Normalization Form C. Since WSDL is defining an XML document, which is defined as a sequence of Unicode characters, this is really a consideration for the XML processor, I believe, rather than something WSDL itself needs to address.

1c. is basically a no-op: it covers normalization of IRIs already in a Unicode encoding (you don't normalize if the IRI is already in Unicode).

So the difference is the application of (1b) when the document is encoded using a non-Unicode encoding, something that probably doesn't apply to WSDL directly anyway: it is something that happens at the XML processor level, XML documents being a sequence of Unicode characters...

In any case, I agree with Martin. I would suggest text more like the following instead:

--
Note: The xs:anyURI type is defined so that xs:anyURI values are essentially IRIs [RFC 3987]. The conversion from xs:anyURI values to an actual URI is via an escaping procedure defined by [XLink 1.0], which is identical in most respects to IRI Section 3.1. (The only difference being that IRI defines handling of non-Unicode encoded byte sequences, considerations which do not affect this document directly.)
--

Best Regards,

Addison
