If that is the question (it seems a good one), then the problem would
appear to be much harder, since what you really want is conditional
formatting properties depending on whether 'some' elements contain
only ignorable white space (in the XML sense). But HTML is not XML, and I
don't think HTML parsers can flag this difference. With XML. I suppose
that the formatting software could take each element, do a test on child
nodes, test on the text content (if the element only contains text), and
then set display:none for 'appropriate' elements, but that seems so venal
that I can't imagine it become a recommended practice...  If that proved
to be the only way to do this,  I'd rather live with empty <p>'s
that produce spaces :(
