The data need not be limited to items that are present in the font data.
And it's a safe bet that many tool makers - think browser add-ons - will
prefer parsing simple XML name-value pairs (something they already routinely
do) rather than making sense of OpenType binary data.

That would be up to the vendor, imo. If there is data they want to show
to the user that is not included in the current schema, I'd rather give
them a very simple and constrained mechanism to do that rather than having
this WG revision this schema 10 times in the next 5 years with each browser
rendering different versions of it.

Yes. Exactly my suggestion. Vendors may add name-value pairs here. No
open-ended markup, only named strings.
