    <!-- The repository contains a collection of downloadable items known as
         "packages". Each package has a type and various attributes and contains
         a list of file "archives" that can be downloaded for specific OSes.

         An Android Addon repository is a web site that contains an "addon.xml"
         file that conforms to this XML Schema.

         History:
         - v1 is used by the SDK Updater in Tools r8. It is split out of the
           main SDK Repository XML Schema and can only contain <addon> and
           <extra> packages.

         - v2 is used by the SDK Updater in Tools r12.
            - <extra> element now has a <project-files> element that contains 1 or
              or more <path>, each indicating the relative path of a file that this package
              can contribute to installed projects.
            - <addon> element now has an optional <layoutlib> that indicates the API
              and revision of the layout library for this particular add-on, if any.

         - v3 is used by the SDK Manager in Tools r14:
            - <extra> now has an <old-paths> element, a ;-separated list of old paths that
              should be detected and migrated to the new <path> for that package.

         - v4 is used by the SDK Manager in Tools r18:
            - <extra> and <addon> are not in the Repository XSD v6 anymore.
            - <extra> get a new field <name-display>, which is used by the SDK Manager to
              customize the name of the extra in the list display. The single <vendor>
              field becomes <vendor-id> and <vendor-display>, the id being used internally
              and the display in the UI.
            - <addon> does the same, where <name> is replaced by <name-id> and <name-display>
              and <vendor> is replaced by <vendor-id> and <vendor-display>.

         - v5 is used by the SDK Manager in Tools r20:
            - The <beta-rc> element is no longer supported. It was never implemented anyway.
            - For <tool> and <platform-tool> packages, the <revision> element becomes a
              a "full revision" element with <major>, <minor>, <micro> and <preview> sub-elements.
            - <min-tools-rev> for <extra> becomes a full revision element.
