The HTML and everything else, according to recent group discussion and  
resolution.

Well, if you are trying to make stuff that you can send to an unknown  
mobile phone, there are fairly strict limits about what it can handle. (We  
have moved forward - the first phone I used for browsing the web, in 1999,  
could handle about 5k I think.

Not all content meets Mobile Web Best Practices - which is not to say the  
content is evil or bad, just that it is not something you should expect to  
work well on most mobile browsers.

One issue is that there are many phones and other small devices out there  
which are much more powerful than the Default Devliery Context. On the  
other hand, there are quite a lot of deployed WAP-only browsers that are  
not even that good, and people make a lot of money adapting pages to  
deliver to them. You can of course pay the money to the experts, who will  
take almost anything and find a way of serving some form of it to a phone.  
If you're trying to do it yourself, the Best Practices are a guide to,  
well, best practices for making stuff that will work. (Note that they also  
encourage you take adapt your content where possible and relevant...)
