i had understood {"","a",""}, from the example, to denote a name in a namespace for which there would have been a declaration, namely a binding such as <... xmlns="" ... > for the ignominious "null" namespace. how does this come to correspond to { undeclared, "a", valid-prefix } ? i agree that an "==" implementation needs to account for this, but didn't think it was nonconformant.
