Re: [RDFa] ISSUE-3 @class and @role for rdf:type

Let me try and summarise the positions as I see them

For class:
	Used by microformats in a similar way
	HTML Spec allows it
	Already there, no new attribute
	Implementations already using it

Against class:
	Special rule for namespaced/non-namespaced values
	Confusion/objection by/upset for current class users
	Used by microformats in a similar way

For role:
	Clean start, no legacy
	No special namespace-prefix rules; can use default namespace rules.

Against role:
	Potential conflict with WAI use of role needs to be resolved

For yet another attribute:
	Clean start, no legacy
	No special namespace rules

Against yet another attribute:
	Yet another attribute
