Two comments. The first is on the namespace registration template found in section 8.2. It says:
"This section registers a new XML namespace, as per guidelines in URN document [4]." [4] is:
[4] Mealling, M., "The IETF XML Registry", RFC 3688, January 2004.
There are two problems with the above.
1. 3688 isn't really a URN document. It describes procedures to register URNs, but it is better described as the "IETF XML Registry".
Ok.
2. Section 3.2 of 3688 describes what gets registered when registering an XML namespace. It says "XML Namespaces ... are named by a URI. They have no real, machine-parsable representation". Yet the template includes a chunk of XML to be registered. It's not needed, so why is it included? All that needs to be registered is the urn:ietf:params:xml:ns:simple-filter URN.
That's how I've seen it done. Check out http://www.ietf.org/rfc/rfc3858.txt and http://www.ietf.org/internet-drafts/draft-ietf-simple-iscomposing -03.txt (in author's 48 hours)
Second comment: the schema in section 6 includes several elements and attributes that allow extensibility, including "<xs:anyAttribute namespace="##other" processContents="lax"/>" and "<xs:any namespace="##other" processContents="lax" minOccurs="0" maxOccurs="unbounded"/>". I don't see any text in the document describing just how these extension elements and attributes are supposed to be used, though. You really should add some text to describe the extensibility framework. What's allowed? What isn't? What needs to be done to avoid namespace collisions and version conflicts?
Will add some text. Thanks, Hisham
