Content Management Systems and DI conformity

Greetings,

I'm trying to find CMSs that conform with what the DIWG drafts propose.

The impression I've gathered from what I've read here is that DI publishing 
as such is not yet a reality.. at least with regard to conventional CMSs. 
How true is this, given of course that the DI Drafts are still not yet 
formal standards?

If there is no DI publishing toolset or "suite" per se, which CMS or 
packages come the closest and which are the hopefuls?

Also, what are the choice tools for development if there are no 
"ready-to-wear" development solutions? Which sets of tools are being used 
vis-a-vis CMS-type environments?

Take a site like cmsmatrix.org. If I were to browse trough such a listing, 
and seeing as no product claims conformity with Device Independence, what 
guidelines could be applied to best sort through the various products? If I 
ask on their mailing list, they're likely to refer me to the DI list with a 
request for clarification.


Thanks again,
Julian.
