I'm actually not sure. I believe the intention is for implementations to 
use the standard UUID format, but some legacy content repositories could 
also use custom identifiers (the global identifiers in Notes would be a 
good example).

commons-id sources (see bug 35820 in the Apache Bugzilla), but the 
change never propagated to Jackrabbit as we perhaps should consider 
making commons-id a normal dependency once it moves out of the commons
