We need to step up to database functionality

Erik and I have been having an email exchange related to paging and, essentially,
page stability.  In the database world this is called cursor stability, See:

But I want to touch on a broader issue.  With LDP we allow multiple users access to a web resource,
and some of these users may be able to update the resource or some part of it.  This takes us into
database territory but we have steadfastly chosen to ignore functionality like
- access control
- transactions
- locking

We need to consider these because it will come back and bite us in the butt when, for example, users'
updates are partially reflected (transactions).
