Thanks for the reply.... an additional question about container types.
From what I have read my sitiation with a large number of very small documents
where I will always be returning the whole document through a query and
replacing the whole document for updates, the best choice is to use a Wholedoc
container. Is that correct? Also it is still possible to define indexes on nodes
and attributes when Wholedoc is used?
