Hi Tantek,
I've just read your mail exchange with my colleague Mike [1][2][3] and I  
wanted to add few comments on that thread as well as extend the discussion  
to the Web&TV IG, as there could be other people that may have an opinion  
on this subject.

In short, the CSS Basic UI spec [4] mark nav-* properties as at risk, and  
you seem to agree they should be dropped.

As already mentioned by Mike in [1] and [3] , we (Opera) do recommend use  
of nav-* properties for our TV store Apps, and AFAIK so far we haven't  
received any complaint (this doesn't mean there are no issues of course,  
but at least we haven't heard of any)

Furthermore, as also mentioned by Mike, there are other specifications  
referencing CSS nav-* properties, namely HbbTV [5].

The HbbTV specification, although not aimed to the "Open Web", it's still  
a public specification and is currently supported in Europe by many retail  
devices (mostly TVs and STBs), not only Opera based but also Webkit based

Also in this case, I haven't heard (so far) any complaint from (Hbb)TV  
apps developers.

Given the pointers above, can you help me (us) understand what is the  
problem with css nav-* properties and why you want to drop them? As they  
seem to be used and supported by different browsers, would be possible to  
investigate more in details what is working (and what is not) and maybe  
drop only the problematic parts (if any)?

I appreciate you may have debated this at length before on the www-style  
list, but I was wondering if for the benefit of the web&tv folks you could  
summarize the issues and provide related pointers.

Also note that personally I haven't done an in depth analysis of the spec  
and/or the implementations out there, but I wanted to get this discussion  
started ASAP as the deadline for comments is already passed.
