I've deliberately quoted "namespace": a simple prefix is enough.

As an example consider that a web page might already use class
"description" for its own purpose. Suppose now that he'd like to add
hCalendar encapsulation: how he can easily represent differently the
hCalendar content and the others?

He has some alternative:

1) don't use the "description" class outside hCalendar data (??? to use
hCalendar means to be forced to not use any rfc2445 names as class name?)

2) use selectors like:
.vevent .description { }

but what about if .vevent area is rather large and inside that he
already use some classes clashing with rfc2445? And what about if vevent
internal data is stored outside .vevent area?

Consider also that to have a "namespace" does not inhibits the web
designer to use the same microformat classes for normal CSS as you write.

You should only solve the problem of how to instruct stylesheet about
*where* it can find the role param value in xhtml page... And then you
should be sure that with this policy you're not excluding *any* sensible

You've an hard work, my friend... :-)
