Ho. I am quite surprised, since TOPCAT (and presumably the MS viewer)
use off-the-shelf XML parsing components which I'd expect to be handle
all this sort of thing correctly; so my suspicion would be that there's
something subtly wrong with the XML. If that's not the case I'd like
to understand what went wrong anyway. Could you pass me the XML file
so I can take a look?
In any case, as you suggest, this does underline the point that keeping
it simple leaves less to go wrong.
