can you send that to me that I can give it a try

what do you mean by doesn't add much value?

Well, I think it would make sense to stick to the source and map nodes
onto collections and properties onto resources.

But yes, as an alternative we could write a specific JCR Generator.

But one of the main questions probably is, can we (Cocoon community) 
agree on something. At the moment it seems to me that only Sylvain's 
company and
the Lenya community is using the JCR source, but want to use it in different
ways, right?

No offense, but it seems to me that the current JCR Source isn't very 
useful,
beside being able to list all the nodes, or am I missing something?

Thanks

Michi
