Quantify that some. My experience with a large database is that
after it is used for awhile, it is remarkably stable. The changes
for the most part tend to be extensions of new tables or a field
here and there. Further, the areas where there is a higher rate
of change is usually encapsulated and more often deals with the
system tables (the data driven aspects of GUIs for example).
Given that an XML system may be comprised of multiple schemas,
it should be reasonable to isolate high rate of change data
definitions from the stable ones. So a question then is how
well does the database handle multiple schemas? Of course,
relationships are affected (eg, XLinks) and one has to figure
an impact there as well.

E.g. if your schema is in a constant state of change (and they probably all
over time) or has yet to be finalized/standardised then locking it into a
database structure might be unwise. Or am I off track on that one?
