If you can’t clear out enough “junk” with the to_xml options:

http://api.rubyonrails.org/classes/ActiveRecord/XmlSerialization.html#M000910

then override to_xml on your model to produce the xml you want…
probably with builder. You can also make a builder rxml template and
have the controller render that instead.

aha, i can use “kip_instruct => true, :except => [ … ]”.

Thank you very much!!
