Hi Roger,

As Michael stated, both these instances are indeed valid and the latest
release of XMLSpy 2007SP2 flags them both as valid. In this case you
must be using a previous release of XMLSpy that flagged the instances as
invalid. I replied to you off-line earlier and you're welcome to
follow-up there!

These instances are valid.

People often misread this bit of the spec, because it's very badly
written.
What isn't immediately clear is that when it talks about the lexical
space of the data type, that isn't the value as it appears in your
source document, it's the value after applying any processing implied by
the whitespace facet. In this case, applying the whitespace facet
creates a value that satisfies the rules for the lexical space.

The fact that xs:token is such a ridiculous misnomer for this data type
doesn't help...
