Proposal 13056: Extension to syntax for built-in selection attributes

I like this proposal very much.

The one thing that comes to mind is adding, or at least mentioning as a
possibility, the use of subjectScheme maps to declare and validate
user-defined groups.

That is, I'd like the option, as a DITA system administrator, the option to
formally define what groups authors should be allowed to use by using
subjectScheme maps, which I would likely already be using to define value
uses for use in conditional attributes.

I'm not sure what would be required--I haven't thought this idea through and
I wouldn't want something like this to overburden the proposal, but it seems
like a natural extension of the current use of subjectSchemes for defining
attribute value lists.

Cheers,

E.
