I'd prefer to see a requirement. I'd also require to warn if same prefix is declared via xmlns: and @prefix for different URIs; "the mapping from @prefix must take precedence" can masquerade errors so a document will be parsed in two different ways by RDFa 1.1 parsers and by (my own) obsolete parsers. OTOH, if I were the initial developer of the web, I'd fill all tools with warnings, and now the web would be an accurate, well-organized... cemetery without any live people ;) Best Regards, Ivan Mikhailov OpenLink Software http://virtuoso.openlinksw.com
