In effect it's about simplicity, OtherInfo is much easier to use both
for people writing info providers and for clients trying to use it.
However, for some things it may not be sufficient, and Extension can
provide more structure if it's needed. Indeed, if we allowed Extensions
to have Extensions of their own you could potentially build a whole
custom schema within GLUE - although whether it would be a good idea
might be questionable ...
