According to HTML5, default inclusion in the tab order is not decided
by whether it is interactive but by 'platform conventions': [1]
]] If the attribute is omitted or parsing the value returns an error
The user agent should follow platform conventions to determine
if the element is to be focusable and, if so, whether the
element can be reached using sequential focus navigation, and
if so, what its relative order should be. [[

However, perhaps the spec needs to *specify* that it must belong in the
default tab order? Thoughts?
And, btw, what about @cite? @cite is only accessible via context menu,
AFAIK. This is also, in my view, an issue for text browsers like Lynx.
(Text browsers could have implemented support for @longdesc and @cite
in a fashion similar to how they implement support for image maps: for
image maps one must "walk into" the image to retrieve the list of links
of the image map.)

Eh ... Meant @longdesc.
