Hi, This is a QA Review comment for "XHTML 2.0" http://www.w3.org/TR/2006/WD-xhtml2-20060726/ 2006-07-26 8th WD
About http://www.w3.org/TR/2006/WD-xhtml2-20060726/mod-meta.html XHTML 2.0 Specifications says: "This specification defines a small normative set of properties, but users may extend this set as described for the property attribute." The only "definition", I can read in the linked document is in section "24.1. Metadata Attribute Collection": http://www.w3.org/TR/2006/WD-xhtml2-20060726/mod-metaAttributes.html#col_Metainformation "The list of predefined values (in the XHTML2 namespace) are given below. Users may extend this collection of relationships, however new values must be defined in their own namespace, and the relationship names must be referenced in documents as qualified names (e.g., dc:creator for the Dublin Core "creator" relationship)." It has been one of the major problems of the profile attribute in HTML 4.01, there was no formal definition on what should give the URI. No defined common format, which didn't leverage interoperability and make machine processing of value easy for the author. In a User Interface if a model was clearly, it would make it possible for - User agent to display the definition of the property if requested (accessibility, usability) - Authoring tool to display a menu with choices of values and their definition when editing - Search engines to index content with help on definition when someone is using the search engine. -- Karl Dubost - http://www.w3.org/People/karl/ W3C Conformance Manager, QA Activity Lead QA Weblog - http://www.w3.org/QA/ *** Be Strict To Be Cool ***
