Exposing generic XML as Sling resource

[Julian Reschke]

Hi Sling Devs!

I've been looking at exposing generic XML as a content tree, and - after 
considering implementing JCR level 1 on top of an XML DOM - was pointed 
to <https://github.com/apache/sling-org-apache-sling-fsresource>.

This looks promising as (1) the Sling resource API is less complex, and 
(2) the fsresource provider already is close to what I'm looking for.

I was looking at the source, and adding a new FSMode and a new Wrapper 
seems to be the obvious approach.

Does this sound right? Anything I'm missing? Is there some other 
extension point/module I should look at instead?

Best regards, Julian
