+1000 (I think I said that already)

Actually it shouldn't matter if you are wyona or korosec, because they
both have permissions to create the doctype "Members". But only once!
Because each "Group" has only one "Members" overview, but arbitrary 
number of members:-)

That's right. Lise is taken as sample. It would certainly be better
the way as you suggest it. I changed it (public CVS!)
You find the samples at:

docs/publication/doctypes/samples/

The layout was given from the ETH (Swiss Federal Institute of 
Technology), which means the Search Field is part of the layout, but
we didn't implement it. For searching there various possibilities.
Our strategy is actually as follows:
Every time you modify some content, the change will be noticed
by the "Revision Controller" (we are currently migrating and 
refactoring). The Revision Controller will notify the Dispatcher, which
will notify the Search Engine to index the modified content 
(Publisher-Dispatcher-Subscriber Pattern). This way you can add
any Search Engine as Subscriber to the Dispatcher. You can also add more
than one by using this pattern. It's really very powerful!

It's based on the "tree.xml" (Will put that into some XML DB e.g. 
XIndice and XPath). But I think you wrote something because of 
Performence Problems!?

That's right, it's not that nice, but we wanted to show, tha you can 
have external links within the tree.

Sorry for that, but the HTML-Form editor is just a prototype and
we didn't have time yet to further enhance it.

No not really. It's a sibling. The order is based on time when the 
sibling was added!

Correct. No this feature is not there yet, but it would certainly be a 
nice feature!

It's part of "their" (ETH) design.

That's quite probable. Cocoon eats a lot of memory. Our PC's have 1 Gig 
of memory and we are actually free of memory problems. But you might try
out -mX. See also the preformance guide from Cocoon!

Thanks a lot for your comments on ethz-mat
