This is nice summary for new users like myself. Thanks.

Should the generator be custom coded or are there any
cocoon pre-built generators which would create XML
from request attributes & transport objects?

I'm thinking of the case where transport object is an object
representation of a hierchical database data.
Are there any open source products which can be used
here to do the transformation from object/relational to XML?

Thanks
