In my opinion, this is not necessarily the best solution. If, at one  
point, someone
wants to add additional properties to UID, this will be impossible  
since UID is
then a locked subset of hCards.

The same thing is happening with "geo" at the moment. Altitude and date
information is certainly useful in geo but can't be added because no  
to geo are accepted, since they are not in vCards and subsequently  
not in

Will UID be locked too, just like geo? If this is not the case, then  
I'm fine with
using UID for ISBN/ISSN numbers. Protocol style identifiers (isbn://)  
and type
identifiers (<span class="type">ISBN</span>) are both very good  
and have worked elsewhere.
