I intended to mean all serious implementations which currently exist and 
which I was aware of and which I had tested, which were listed in a 
later paragraph.

(It would also include any conceivable implementation that uses a 
conforming HTML5 parser, which would be a prerequisite for conforming to 
any sane RDFa-in-HTML5 specification, unless the HTML5 parser spec is 
changed in ways that seem very unlikely because of compatibility issues.)
