[widgets] User agent conformance

   According to the latest editor's draft (20 may 2008), a conforming 
widget user agent needs to support zip/deflate, png, gif, xml, xmlns and 
DOM3CORE. However, a conforming widget resource can also include other 
kinds of contents (eg. SVG, SMIL, etc.) Thus there is no way in the 
current draft for a user agent to check beforehand if it will actually 
be able to run the widget. A solution could be to add in config.xml the 
list of additional mime types a user agent must process for a given 
resource :
<widget xmlns="http://www.w3.org/ns/widgets"
         id="http://datadriven.com.au/exampleWidget"
         version="2.0 Beta" height="200" width="200">
   <name>The example widget!</name>
   ...
   <requires mime="image/svg+xml"/>
   <requires mime="application/smil"/>
</widget>


Also, in §5.2 [1] it is said that support for text/html is required. 
Should this be added to §3 [2] ?
