In Swignition I implemented a handful of X-* properties, though this was
a list of additional properties recognised by the parser rather than
just allowing the page to specify arbitrary classes beginning with "x-".

<span class="category">Salary - €50000</span>
<span class="category">Shoe Size - 10.5</span>
<span class="category">Favourite Pizza - Pepperoni</span>

Then skim through categories doing something like this (Javascriptish
pseudo-code):

	$data = new Array();
	foreach ($vcard.category as $category)
	{
		if ($category.matches(/ - /))
		{
			($key, $val) = $category.split(/ - /);
			if (!$data[$key]) $data[$key] = new Array;
			$data[$key].push($val);
		}
	}
