If I understand the heretoforegoing (and I am not at all sure I do),

There is no reliable way to know if you are begin accessed by a mobile  
device. So unless you serve, by default, a mobile-friendly version from a  
given URI, there is no obvious way to be friendly to mobiles.

What may happen is that a detection approach can be used to find a "more  
capable" browser and send adapted content to it, optimised to take  
advantage of its capabilities. So the risk is that if the system thinks  
your browser can handle foobar, it sends it. (This is why WAI should have  
been thinking about describing preferences in CC/PP. But it's probably OK,  
other people are doing that through other fora now.)

The workaround is to change what your system says it is (like Opera does,  
claiming to be less capable in order to get the default presentation, but  
for different reasons).

Dunno

Yes, by and large...

> Has the markup in mobile pages gotten away from standard HTML?

Not really. It has moved towards it in general, as more phones have become  
HTML capable. (About 1.1 billion WAP phones. About 700 million of those  
handle the normal web, although this is a relatively new development - a  
year ago the pro)portion of real web phones was a lot lower. On the other  
hand, they get used more than WAP. Firefox and Opera both handle WML on  
the desktop, too)

In general, no.

Is this different from the first question?
