Adding QUDT to RDFa Initial Context

I have no idea what the procedures are for adding things to the initial
context [1] but I'm going to throw this one into the mix.  I would like to
see prefixes for the QUDT vocabulary [2] added.

"The excellence of grammar as a guide is proportional to the paucity of the
inflexions, i.e. to the degree of analysis effected by the language
considered."
