Hi Ramon--

When we evaluate sites we treat the frames as separate pages, and the iFrame wrapper has its own identity. You'll also need to review the entire page (wrapper + iFrame) together, however, so you can evaluate their interaction. 

Btw, you've already identified one failure on the site that is a common problem with frame-based websites: that the page title doesn't change to reflect page content. 

Hope this helps.

Of course, each loaded content has its own, different URI, but they are "embedded" resources that cannot be evaluated without the contents of the parent page.
