Hi,
can someone clarify the meaning of the following bullet in Section 11,
RFC7950:
o A "base" statement may be removed from an "identityref" type,
provided there is at least one "base" statement left.
This seems to enable the value space of a definition to narrow across
revisions of the same module.
"base" statements are ANDed, so removing one expands the value space.
9.10.2 says:
Valid values for an identityref are any identities derived from all
the identityref's base identities.
Oh, my. That is not how I understood "identityref"s with multiple bases
worked at all.

Most other changes in this section seem
to only allow expansion of the value space, relaxing of constraints,
etc. What kind of revisions does this bullet cover?
