Hi Dom,

I've been following the mobile checker list. Excited to see it go in  
beta soon!

Right, I'd rather we had tools communicate than duplicate code, unless  
there is a massive performance gain.

If I understand correctly, there is a need for the UA checking the  
online resources to clearly identify itself as a mobile agent, so that  
proper content adaptation/selection on the server side take place, and  
it would be important that the markup validator do so?

I guess that is feasible. I am not a big fan of advertizing the User- 
Agent strings of our checking tools because some people will make sure  
that the validators get valid content while others still get crap (or,  
in the case of ASP.net driven sites, the opposite) but I understand  
your needs.

So, basically the need would be to:
- define a validator call parameter saying "identify yourself as"
- trigger sending a different UA string based on this parameter

BTW, there is a validator release due in a few days, if we're fast  
enough we may be able to add this in.
