performance (since the dom is stored and not the source)
fast query's

example:
i currently have a poll running (a simple xml file that contains polls + answers + answer count)
i dont have to worry about loading and saving the file.
i can just perform a Xpath query modify the right node
after that i convert the database dom to a memory dom and pass it to cocoon.

if i wans't using the database i would have to load the xml file to a dom
perform the Xpathquery change  the values and than save it. Now happends when 2 users try to poll at once etc etc.


de database is/wil be able to perform checks
- i know the document in the database are wel formed
- i can give rights
-using XpathQuery's over te (to come) repository i wil be able to maintain constitency (witch documents have a link to this files)
