Yes, that's along the lines I would anticipate.

There's a reasonable debate to be had about whether EPAR data belongs at 
the WOFF container level, the font data level, or both, but if you're 
looking for a use case for the extension metadata I think one could 
start with looking at David's EPAR draft (link?) and determining how 
that data could be represented within extended WOFF metadata. It's a 
good case of what font makers might want to include.

Regarding localisation, I believe that licensing, trademark and other 
legal strings are most likely to be localised. Will all or even most 
fonts contain localised strings? Probably not. Most OT fonts don't 
either, but some do. We produce fonts for a clients in countries where 
English is not the first language, for local scripts and languages, and 
being able to localise data in those languages is a welcome option to be 
able to present to clients.
