>From a users point of view I think it is important that a document is
stored in one file, if not, there would be some problems

* how would you know which file is the root document
* how would you know which files belongs to the document
* how are the unneeded components `garbage collected'

However there are benefits of storing the components one by one.

* if there are many large components it may be slow to save after a
  small change, an example would be a large high resolution DTP
  document

A solution would be to design EFS so that it is transparent if the
true file system is used or the EFS is used.

I didn't quite get why the EFS should be anti-XML, if you can have
href's to components inside the EFS.
