I think that very few know, since they are making things overcomplicated ;)

Afaik (which is not a lot)  here you can find the most general way for
encoding rfid data:

http://www.epcglobalinc.org/standards/tds/

To make the story short the urn scheme is something like this:

urn:epc:id:gid:1.1.100

where
 - epc tells that you are encoding things according to those specs
 - id means that the urn refers to a pure tag id (there more complex
schemes for application dependent data, filters...)
 - gid: the identity type, says that is a general id, indicating that
the following id must not be interpreted for a specific purpose such
as a shipping number or a product code
 - and finally finally the numeric id

Therefore in the <id/> element I'd put the EPC urn, and than let the
application give it a meaning according to the used encoding
