No, no, you're missing the point.  I'm looking for non-nested elements.
<foo><bar /></foo> is a reference to parent and child nodes.

I'm looking for, more or less, something like:
<foo>[content]</foo>
<blah>[content]</blah>
<bar />

whereas the <foo>...</foo> and <bar /> elements are seemingly unrelated in
relative to the markup.  The idea is to control the behavior of <bar />'s
style through interaction with the <foo>...</foo> element.  See what I'm
saying?
