While I agree with the "problems" of this example, I must agree with 
Lachlan's comments, in that the example is completely correct XHTML 2, 
and thus bears no need to be changed.

CSS authors can even (with CSS3 Selectors) check the exact src 
attribute, or even check for the existance of an src attribute to style 
differently, though this is "slightly" problematic if the content cannot 
be loaded by a specific UA, issue's such as this should be considered by 
the XHTML 2 author, and with the advent of this issue, my hope is that 
someone could propose a CSS change to reference this need.

Specs are not standalone, yes.  Though they should be strongly 
targetted, and XHTML 2's goal is structural/content not presentation, 
thus the CSS issue is not one to warrant _any_ change in the examples or 
actual uses of the spec [imho].
