Doug, your thought process seems to be correct - however, the SVG Tiny LC Draft does not quite reflect this thinking, IMHO. Each time I read the section on RDFa/Microformats I get a different impression. http://www.w3.org/TR/SVGMobile12/metadata.html#MetadataAttributes """ # When used with RDFa, the values for the 'rel' and 'rev' attributes must be a CURIE [RDFA] (i.e., a prefixed string, such as 'cc:license' to indicate a Creative Commons license), while the values may simply be from a set of specific keywords for Microformats. These formats may be used independently, or in combination if the keywords do not clash. """ One impression is that SVG Tiny only allows "prefixed strings". The other is that SVG Tiny supports both "prefix:reference" and "reference" CURIEs? The latter, supporting the complete CURIE specification, is the preferred one as far as the RDFa Task Force is concerned. This would allow both RDFa and Microformats to exist in the same SVG document AND it wouldn't prevent RDFa parsers from recognizing reserved words (like those defined for @rel/@rev in XHTML+RDFa or XHTML2). The more I read the paragraph, the more I'm convinced that it's just a wording issue. -- manu -- Manu Sporny President/CEO - Digital Bazaar, Inc. blog: Bitmunk 3.0 Website Launches http://blog.digitalbazaar.com/2008/07/03/bitmunk-3-website-launches
