Or, more widely, web content is anything that can be displayed/rendered 
directly from a URI without the need for it to be downloaded locally to 
a user's environment first (though even here issues of local cache for 
UAs may need to be at least aknowledged/outscoped). And a user agent is 
anything that can access and display/process web content directly from a 
URI without the need for it to be run locally, of sorts? Still circular 
reasoning, but at least includes explicit mention that it needs to be 
done directly "from the web" if you will.

If that was the original intent even in WCAG 2.0, this would be an 
editorial change, rather than a substantive change, that should be easy 
to incorporate into WCAG 2.1?
