The full pipeline II schema is available at:
http://glast-ground.slac.stanford.edu/Pipeline-II/schemas/2.0/pipeline.xsd
The maven generated pipeline II web site contains full documentation on the XML schema automatically generated from the source.
When editing an XML file for the pipeline, you are encouraged to use an editor which can validate XML files against XML schema, since this will save you a lot of time. EMACS users may be interested in this guide to using XML with EMACS.
