Hello Terence,

Thanks for your detailed reply.

Then, ISO HTML has not any accessibility advantages over W3C HTML 4 or XHTML.

The decisive drawbacks, for me, are:
1) Headings are not allowed in a DIV container;
2) Cell phones (always?, most often?) use XHTML.

Other drawbacks:
1) Few editors support ISO HTML;
2) No support for scripting.

I did not know that ISO HTML is a subset of HTML 4.01 Strict. I thought it was the other way around.

Regards,
Thomas Jedenfelt
