I've updated the FAQ to reflect that.
I've still seen no citation for any *prohibition* of hidden data in
microformats...
I do think there is a valid case for being able to have *some* hidden
items where humans can easily work out from other stuff that IS
displayed what they are
but machines may still need them
- such as the case that was discussed here a few months ago of
displaying the (adr or hcard) region or country in hcalendar items
where it is assumed that people looking at the page would already know
them because all the events are in the same city (the summary, dates,
description, etc would still be visible) or where that information is
already present in a human-readable form somewhere else on the page or
it is obvious to humans (such as a site or section of a site about a
certain city)
I'd say it is still better to include that extra information even if
it has to be hidden!
- that extra data can still be useful to aggregators/search
tools/export tools etc - and may in some cases be needed.
I don't think there should be ever be any case where visual design
considerations cause people to omit important data,
they should still be able to include it somehow.
Forcing people to display EVERYTHING might cause lots of people out
there to omit potentially useful data.
Another way of "legally" hiding microformats without really hiding any
information is to replace the text with images with the help of CSS. If
you asked the borswer or some other program if the microformat is hidden
it would then say yes - but the info could very well be visible in
graphics. Perhaps a map has replaced some geo-data or a very beutiful
headline has replaced the name in a hCard.
