That means: you take the prefix and look it up in the set of in-scope namespace declarations. If there is no prefix, the attribute ends up in no namespace. Perhaps it doesn't say this in pedantic detail. However, the process of expanding a lexical QName is fairly well understood: when there is no prefix, you either use the default namespace, or you end up with a name that is in no namespace; this text makes it clear that you don't use the default namespace, therefore the only option left is to end up in no namespace.
