[topicmapmail] TMDM serialization

[Borislav Iordanov]

Well, yes, but this is assuming that no other item identifier has the same
format. For instance, suppose the IRI of the topic map is http://foo.com/tm
and we have a topic:

<topic id="x"> 
  <itemIdentity href="http://foo.com/tm#y">
....
</topic>

we end with two very similar identifiers:

http://foo.com/tm#x and
http://foo.com/tm#y
