Just one slight comment:

The ongoing GoodRelations integration will add a property http://schema.org/category. It will at first be constrained to be used with the types

http://schema.org/Demand (new)

It would not harm from the perspective of the GoodRelations usage to widen the domain to http://schema.org/Thing, but in general I think that media-types deserve a more specific pattern.

Enumeration is also the place where we decided to generate specific Lists of Intangible classes of things without generating much fuss about it.  I think the broadcasting & education folks would probably like this specific type and I think it would also be useful across the Internet community at large.

This does 2 things.  It allows an easier entry to Schema.org extensions themselves.  And it lets you additionally categorize with the additionalType property if need be, and can be applied across all use cases and where LRMI and others can perform their external vocabulary magic without the bounds of Enumeration (flat lists).   For those in doubt, I refer to the actual description of additionalType property that we discussed and published http://www.w3.org/wiki/WebSchemas/additionalTypeProposal :
>  An additional type for the item, typically used for adding more specific types from external vocabularies in microdata syntax. This is a relationship between something and a class that the thing is in. In RDFa syntax, it is better to use the native RDFa syntax - the 'typeof' attribute - for multiple types. Schema.org tools may have only weaker understanding of extra types, in particular those defined externally.
