This is the same approach that has been taken for the LDAP implementation. To make this possible, IDs must be globally unique. I support this approach as it lets the implementation to be less coupled to the technology used and facilitates interaction between different systems.

This sounds like what I've been suggesting for LDAP - that we should
view the schema as basically a collection of independent objects linked
together by embedded references, and any structure you get from the
implementation (LDAP tree, XML hierarchy) is incidental.
