[uf-discuss] UID in iCalendar

[Tantek Ç elik]

Agreed with Brian's interpretation.

In addition, I think if we make a stronger suggestion (perhaps a SHOULD)
that individual hCards and hCalendar events have a unique-to-the-document
'id' attribute on their root elements, then automatic construction of
globally unique UIDs becomes fairly straightforward, and we can write an
"implied UID" rule for hCard and hCalendar at a minimum.

Thoughts?  

I'd like to add "SHOULD use 'id'" and "implied UID" to hCard and hCalendar
soon if no one objects.  And yes, we should update the creators so that they
auto-specify uniqueish 'id' attributes on the root elements as well for ease
of authoring.

Thanks,

Tantek
