All,
I've adjusted the HDX overview
<http://www.astro.gla.ac.uk/users/norman/star/java/hdx/> in the light
of folk's comments. Thanks for those.

Done, I think, with the addition of an `abstract', which also now mentions
FITS in the second sentence (thanks, Pat).

I think I've clarified this.

You're right, that unprefixed attributes in such a case are formally in
no namespace, according to the NS spec. However, after much discussion,
Best Practice seems to be to have them processed by whatever application
handles the namespaced element they live in (since what else could they
refer to?), and this is what the HDX software does in fact. Both work
in fact, and .... oh no they don't!
This _did_ work, but I've just discovered that there wasn't a
regression test coverering precisely that, and I must have managed to
break it in the last refactoring. The test is now added, the code is
fixed, so yes, Peter, I can now reassure you the uri attribute isn't
lost. Phew! So _that's_ what regressions tests are for!
But now I've got to rush, so I'll be posting to the dm list later.
By the way, does anyone have an EPS version of the (or indeed A)
Starlink logo? I've got a version created from a GIF I have, but that
doesn't look very pretty. Or the AS&SG logo, of course....
See you,
Norman
