Long story, I doubt there's a solution (as it's a daft requirement) but here are the requirements, maybe xslt 2.0 can help me out here:

This xml:

<node value="£">Hello&#160;World</node>

Once transformed, looks the same:

<node value="£">Hello&#160;World</node>

That is, the non-breaking-space appears as a character reference, and the pound sign appears as the actual character.

I've tried various combinations of output encodings, d-o-e and character maps, but I haven't be able to do it so far.  How would character maps replace d-o-e on attributes here?  Maybe a 'force-output-escaping' would be useful, as it does come up on the list now and again where the answer is to specify an encoding that doesn't contain the character you need in order to force the serialiser to escape it?
