QT approved comment:

In 2.2.3, this sentence is unhelpful: "The value spaces of primitive
datatypes are abstractions, which may have values in common". It's much
better to state unambiguously that the value spaces are disjoint.

(I think what the writer is getting at here is that, for example, an octet
sequence consisting of two xFF octets can appear in both the hexBinary and
base64Binary data types. But it's muddying the waters to say that the two
datatypes have values in common, when in fact the formal model is that they
don't: what you might think of as being the same value is actually two
different and totally unrelated values.)
