Any element, but only on specific Microformat classes, each of which  
has expected RegEx-matchable values. DTSTART, DTEND, DURATION, RDATE,  
RRULE expect values defined in RFC 2445. TYPE and GEO expect values  
defined in RFC 2426. This would eliminate the ambiguity of title-or- 
contents.

	<span class="type" title="foo">pref</span>erred
	<em class="type" title="home">casa</em>
	<li class="geo" title="30.300474;-97.747247">Austin</li>
