2.2.33 [HTML] Section 16.5, Inline frames: the IFRAME element

V0112:

The specification states:

 The information to be inserted inline is designated by the src attribute of [the 
 IFRAME] element. The contents of the IFRAME element, on the other hand, should only 
 be displayed by user agents that do not support frames or are configured not to 
 display frames.

All Document Modes (All Versions)

The content of the IFRAME element is ignored when a site is a member of the Restricted sites zone.

V0113:

The specification states:

 Inline frames may not be resized (and thus, they do not take the noresize 
 attribute).

All Document Modes (All Versions)

The noresize attribute for the IFRAME element is ignored.
