Compulsory:
* Content-type (already is)
* Role
* Name

Optional:
* Language
* Title
* Display-Hint
* Altitude (or should we still change this to z-index or maybe
Display-Altitude ?)

I can just add the fields into the wiki page for skeleton - that won't
be difficult. Or did you want a formal spec such as an update of the
I-D ? Happy to help with either.


Thanks so much for taking control of this!
