Oh, wow. Yes, more explicit documentation in the text would be
appreciated. I completely missed that, even in the CDDL where the key
definitions follow maps referencing them. It seemed like you were using
string keys and relying on general compression to eliminate the bloat, but
this greatly clarifies your "designate as implementation-specific all key
values above a threshold" statement regarding extension fields (and in that
case, might I recommend reserving all nonnegative integers and perhaps also
all strings lacking an implementation-extension prefix for standard key
values? That would suggest negative numbers and prefixed strings for
extension keys, a set encompassing one full major type and then some).
