Sorry for coming late to this, I took my eye off the ball for a week
while panicking about something else.

This fills me with mild horror. The <facsimile> bit, but
that floating @coords on <ab>? with no specific idea
which image it is, or what the units are?

I can relate to that much better (though I still don't get what units
the coords are in), or which image they relate to.
