Ok, I understand what this means...

... but I don't understand these examples.   I expected something
like:

    rev:revision-label-schema yang-semver;

    rev:revision-label-schema semver-2.0;

An alternative could be to use identities:

    rev:revision-label-schema ysmever:yang-semver;

    rev:revision-label-schema ex:semver-2.0;

I prefer a single statement.
