Doesn't this depend if the iframe is from the same origin or not? I know 
I can certainly create cross iframe javascript when the pages are being 
served from the same origin.

The user agent still has access to the inheritance information for this 
so I'm not sure why not specifying the language of an iframe should 
cause any AT difficulty.

Agree - I have no idea how a title element in an iframe would ever get 
communicated to a user.

I've always flagged missing TITLE elements and language attributes as 
potential violations on visible IFRAME elements but I think I have been 
doing this as I believe WCAG is unclear on this rather than based on any 
real fundamental issues which would be observed based on this.

If this could be cleared up I believe I could eliminate developers from 
doing some unnecessary work and allow them to concentrate on more real 
issues.
