Traces of RDFa profiles remain in rdfa-core

Hi,

Are these references to RDFa profiles supposed to remain in
http://www.w3.org/2010/02/rdfa/sources/rdfa-core/Overview.html? I thought
RDFa profiles had been dropped.

The ability to reference RDFa Profiles; these are used to ease authoring by
> creating collections of terms, prefix definitions, and/or default
> vocabulary declarations.


The term mappings, a list of terms and their associated IRIs. This
> specification does not define an initial list. Host Languages may define an
> initial list. If a Host Language provides an initial list, it should do so
> via an RDFa Profile.
