Review Comment:
I would probably return `super.hashCode(`) here and also change line 264 to
return `super.equals()` so if the key can't be extracted only an exact match of
the same object will equal.
We should probably add equals/hashCode methods for the other *KeyValue
subclasses, though we could do that in another PR. Note that the XMLDSig API
does not require implementations to override equals/hashCode. However, it is
useful for testing purposes.
