Agreed.

I'd be in favour of a better term than "known", but I don't think
"declared" is it, because I can easily imagine a type being declared
(in a schema somewhere) but not present in the ISSD. Instead, I think
the clearest abbreviation would be "in scope". That is:

    AT is in scope  (or, AT is an in-scope type)
      ==
    AT is a schema type found/defined in the 'in-scope schema definitions'
