Hello Andrew,
To build on Ben's response:
Imagine that you're building a transport system for shifting piles of boxes
on the back of trailers which are hauled along roads. Where ever you have a
bridge you are going to limit the maximum number of boxes which can get
under it. In order that hauliers know what load they can carry worrying
about bridges, the manager of the transport system mandates that every
bridge must allow at least a pile of boxes 10 high to pass under it. This
doesn't mean that a haulier can't pile boxes 12 high on the back of a
trailer, but if s/he does then s/he needs to either
1) make sure the top 2 boxes don't have anything important in
0r
2) make sure they know the limit of any bridges they pass under, and take
diversions if necessary.
[I think it is important that there is nothing wrong with metadata
instances which excede the smallest permitted maximum, the creator of the
metadata just needs to be aware of the consequences]
Option 1 above shows why it is important that sytems which handle metadata
instances (and pass them on to other systems) don't change the ordering of
elements which can be repeated.
I can't draw either.
Phil.
