I suppose CryptoBinary can still be considered as a restriction of base64Binary.
In other words, it's not an alias, although it behaves like that to some
extent.
I don't see anything in the spec that contradicts my interpretation.
In mathematics, if A=B, then one can usually say that A is a subset of B.
To exclude that possibility, one has to say that A is a proper subset of
B.
