The preceeding discussion of course attracted my attention as
Its bad enough having to explain the difference in my community
between chemical elements and XML elements, without the prospect
of having to do so for molecules and atoms (:-) I suppose
we should consider ourselves lucky that xlink was never called
<bond> (is there a proposal to use the term?)
Add <electron> and <reaction> and you would have most of the CML DTD,
or should I say schema.
I appreciate that the namespaces are different, but still I can
see difficulties ahead with my molecular and atomic
(leaving aside bonded) colleagues!
