  |
  |     This is the initial implementation of the DerivedSections 
  |     schema, intended for use with the IU Infrastructure content
  |     model to denote how and from where a particular metadata was
  |     derived.

  | Version 0.2: 2006/Jan/26
  |    erpeters@indiana.edu
  |
  |    I changed the schema to handle cases where the derivation process
  |    is to be documented in this block, but not able to be automated.
  |    Specifically, I made the sourceRecord tag, and the uri attribute
  |    for the derivationProcess tag optional.  I also made the
  |    derivationProcess tag mixed so that some description could be added
  |    to document the derivation process.
  |
  |    I also added a few more comments within the schema for documentation.
