I know - however it doesn't work...

It wasn't working.

In fact, I never have got any control characters to work within [ .. ] 
yet (except for ^). As this example is documented, I felt it should
work (and isn't just me doing something wrong).

My rule does do the right think, but perhaps that is coincidence in
that Xref usually is the last header.

I managed to get it to create the adapt file, with the correct
reference entries, etc. However, none of the articles were
being highlighted. I don't understand why.

Even more weird, it that scoring of "followups" works fine.
I believe the two are very similar.
