OK, I see the language now, I'm not that happy about a namespace URI for designators, but I guess there is nothing wrong with it. However if that is the usage we intend, can you, when you fix up the language around xml:base, change the terminology of the feature and extension element, to similar wording to that in <profile> so that it mentions the namespace.

A profile designator must adhere to the xsd:anyURI data type defined by [XML Schema Part 2]<http://www.w3.org/TR/ttaf1-dfxp/#xsd-2>, 3.2.17. If the profile designator is expressed as a relative URI, then it must be absolutized by using the TT Profile Namespace value as the base URI.
 Thanks,

Sean

You can close this issue. The answer to this question is already addressed the second paragraph of the note under Table 1 of 5.1, quoted below. In the specific case of the TT Profile Namespace, it is use to label standard profiles as well as provide a deferenceable URL to a TT AF Profile Definition Document.

Note:

If a reference to an element type is used in this specification and the name of the element type is not namespace qualified, then the TT Namespace applies.

For certain namespaces defined above, the default prefix is specified as none if no XML vocabulary is defined in the namespace by this specification (nor expected to be defined in a future version of this specification). In such cases, the use of the namespace URI is for purposes other than defining XML vocabulary, e.g., for designating profiles, features, extensions and for dereferencing standard profile definitions.
