This is true, but I must caution that my tests were only conclusive insofar
as the syntax seems correct as per the ICADD DTD. Using available tools,
each HTML document must be modified by addition of some text in the
declaration subset to cause the ICADD transformation to occur. Obviously
this would not be a good general solution, but could be handled "behind the
scenes" in an ICADD-enabled browser without modifying the document. Having
no ICADD-enabled browser to work from, this was as far as I could go, so
I'm not convinced that the process works (or even did work in HTML 2.0).

I've discussed this with Dave Raggett, but we'd really need some support
from ICADD. I have a contact that may be able to help. Anyone else with
contacts in the ICADD community is certainly welcome to contact me.
