+1 to everything Mark said about collapsing prefix/keywords into a
single concept - "a list of mappings".

The more time we spend discussing it, the more convinced I am that it is
a natural progression that will simultaneously simplify implementations
and lead to a more unified mental model for RDFa. Instead of having to
track two concepts - prefix and keywords, authors will only have to
track one concept - "a list of mappings".

Besides - if we think that authors are capable of understand chaining,
surely they're capable of understanding a "dictionary of terms":

definition -> meaning
definition -> meaning
definition -> meaning

which becomes this in the RDFa 1.1 mental model:

foaf   -> http://xmlns.com/foaf/0.1/
Person -> http://xmlns.com/foaf/0.1/Person
title  -> http://purl.org/dc/terms/title

Contrast this will keeping the concepts separate, there will be two
"dictionaries" that they will have to keep track of in their mind:

"dictionary of prefixes"

foaf   -> http://xmlns.com/foaf/0.1/
dc     -> http://purl.org/dc/terms/

"dictionary of keywords"

Person -> http://xmlns.com/foaf/0.1/Person
title  -> http://purl.org/dc/terms/title

I know there is resistance to unifying prefixes/keywords - but I don't
necessarily understand the argument at this point.
