>From this thread, it seems like the true purpose of irrelevant is to add to HTML the logical equivalent of display:none in CSS. If that is true, then I'd agree with Jeff that renaming the attribute "ignore" or "omit" is a good idea. Can anyone either confirm or deny the purpose of this attribute as the following description:
"This attribute is used to indicate part of a document whose content is not considered primary to the page. In visual UAs, elements with this attribute are not rendered; in non-visual UAs, elements with this attribute are not read as part of the normal content flow."

Unnecessarily suggests a particular medium of display; I suggest the shorter alternatives ignore(d) or omit(ted) if you really want the functionality.
The biggest problem with the attribute is the spec doesn't sufficiently clearly describe the motivation for it; I suggest mentioning the preloading of iframes as such an example (they don't load/render if they're display:none, so it's either visibility:hidden (?) or launching the element into outer space offscreen with position/top/left), perhaps in an informative paragraph.
