the following is an initial draft of a bug in fulfillment of UAWG
Action-447 (http://www.w3.org/WAI/UA/tracker/actions/447)

PROBLEM: @title is not required for FRAME or IFRAME in HTML5

DETAILS: @title has been used since HTML4 by assistive technologies to 
present the user with information as to the nature and function of the 
FRAME or IFRAME for which it is defined.

This is reflected in the Web Content Accessibility Guidelines, Level 2 
(WCAG 2.0) which includes "Technique H64: Using the title attribute of 
the frame and iframe elements"

QUOTE cite="http://www.w3.org/TR/WCAG20-TECHS/H64.html"

The objective of this technique is to demonstrate the use of the title 
attribute of the frame or iframe element to describe the contents of 
each frame. This provides a label for the frame so users can determine 
which frame to enter and explore in detail. It does not label the 
individual page (frame) or inline frame (iframe) in the frameset.

Note that the title attribute labels frames, and is different from the 
title element which labels documents. Both should be provided, since the 
first facilitates navigation among frames and the second clarifies the 
user's current location.

The title attribute is not interchangeable with the name attribute. The 
title labels the frame for users; the name labels it for scripting and 
window targeting. The name is not presented to the user, only the title 
is.
