Hmmm. What I'm getting at is, I think, that there is a resource which
the filter supposedly filters. OK, it may not actually filter it, it may
substitute something different. So, when you view that resource through
the filter, you are at the mercy of the filter. However, if I view the
same resource by another route, I am only at the mercy of the filter if
the filter has permission to modify the resource.

Is that clearer?

Cheers,

Ben.
