strong +1 !

I think the main problems of RDFa, caused by RDF heritage are to repeat aspects defined in the schema/vocabulary in the data markup, like

a) the datatype (if the schema defines the datatype, it is in 99% redundant to repeat it in the instance data)
b) the rel/property distinction (why do I have to look up whether the property is a datatype or object property at markup time if this is defined in the schema).

From the history of RDF being schema-less in the beginning, it is clear why you have datatype and rel/property in RDFa, but I am confident they are now major inhibitors to broad adoption of structured data in HTML markup.
