    <xs:documentation>
        This document describes the schema for the chainer package XML.  This XML is generated
        at build time and added to a package containing an installer.  There are several types
        of installers (RTM, Service Pack, Hotfix) that all use this XML.
        
        ISSUES LIST:
          * Currently the MSI, Configuration, and Upgrade extension data is at the root package
            level.  In order to generalize the package XML they should probably be moved to
            an extension subnode.
