Bjoern is exactly right. (At least on the naming...not about it being
a silly endeavour. :)

In its early days it was called RDF/XHTML, since it was devised as an
XHTML serialisation of RDF. So yes, you are right that the idea was
that RDF/x denoted a way of writing RDF. This was never really
satisfactory, since the idea was always to allow the same technique to
be used in other XML languages.

Since one of the key components of technique was to be able to
'decorate' normal mark-up with meta data via attributes, then RDF/a
soon became preferable, with the only reason for changing from RDF/a
to RDFa being based on nothing more than Google searches, I'm afraid.

All the best,
