[goodrelations] GoodRelations in RDFa: HTML or XHTML?

Hi László,
RDFa was originally designed for XHTML only. They are now discussing
ways to embed RDFa in other markup like HTML5; not sure about HTML4.
You can have a look at the RDFa working group wiki [1] or directly ask
to the RDFa mailing list [2].

HTH,
Irene
