So for OpenType fonts this is simply a wrapper format around the raw
font data included in an archive format (in this case a zipfile)?  Are
there additional requirements for the structure of the fontdata?

I'm wondering who would create these files?  Would authors purchase
fonts in this format or use tools to create these fonts from their
existing library of fonts?  If tools are used to create these you
probably need to say a little more about what that workflow would look
like and where the data above would come from.  Would this data be added
to the font metadata in the name table?

To achieve interoperability you need to have more than simply "Optional"
next to data elements like the "allow" element.  Either it is
informative, provided for displaying information about the font
resource, or has a defined behavior which is consistent across user
agents.
