Looks very good.

Nits: equivalance, assignemnts

I don’t understand this sentence:

   […] For equivalance
   checks, it is RECOMMENDED that lower case letters are used throughout
   by implementations unless there is a reason otherwise.

Does that mean I convert everything to lower case before checking equivalence?  (That’s what this says to me.)  Maybe you mean:

   […] To facilitate equivalence
   checks, it is RECOMMENDED that implementations always use lower case letters where they have a choice in case, unless there is a reason otherwise.

(Also, we usually like to have some idea when a SHOULD [which this is] might not be applicable.)

I probably would like this sentence to be reworded:

   Note that the subtypes defined in this
   document do not require the specific case, however.
