Subject: Mathematical extensions to ISO-HTML

Dear List, 

It is a common reaction on seeing ISO-HTML to comment "The <ABC>
element is missing - thats bad", or "The XYZ attribute is not defined
- thats even worse".

The proposed standard recognises that industrial, national, regional
or international organisations may wish to define packages of
extensions to ISO-HTML, and the specification provides interfaces for
this purpose.  The details are in clause 13 "The extend and addon
interfaces", although note 23 is not yet true.

A frequently mentioned candidate for such a package is mathematics.

If the mathematical community can agree on a DTD fragment sufficiently
rapidly to be able to propose it to JTC1/SC18/WG8 as an annex to
ISO-HTML this would

a) be very helpful to the mathematicians,
b) provide a good example of the construction of such a package.

However this needs to be done quickly.  ISO-HTML will move forwards in
weeks rather than years.
