--- i'll keep this breif because we are toeing that fine-line between
discuss and dev lists. If you want to chat more about this, we can
take this to the dev list.

The problem with random x- prefixes is that a parse can NOT determine
if the value 'dod' is meant to convey semantics (date of death) or
that is purely a CSS style.

For instance:
<div class="vcard">
<span class="fn president blue-box call-out alert">Abraham Lincoln</span>

what becomes 'x-???' in vcard and what doesn't?

FN:Abraham Lincoln
X-PRESIDENT:Abraham Lincoln
X-BLUE-BOX:Abraham Lincoln
X-CALL-OUT:Abraham Lincoln
X-ALERT:Abraham Lincoln

Because of this, there has not been any attempt to add in the 'X-'
parameters into the parsing rules.

If you (or anyone) is still interested, feel free to email the dev-list.
