Hi Hannes,

It's great to hear from you, welcome to the discussion.

You've pretty much covered it all. You should see more by the end of
March, if not earlier.

We haven't discussed using Fresnel as a method for specifying authoring
interfaces. I do believe it could be extended to specify how to present
an XForm or forms in XHTML based on a schema. Were you interested in
taking up an effort to explore that issue?

I would personally think that belongs to the layer that determines what
data is displayed. I can see the relation to display in that the rank
of each object and some UI for navigating pages is necessary, but that
seems like an application specific behavior; i.e., the application that
understands Fresnel should also have its own handler for paging that
works alongside Fresnel to present something to the user.

Fresnel in PHP? :)
