-    <!-- 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 SDK repository is a web site that contains a "repository.xml"
-         file that conforms to this XML Schema.
-
-         History:
-         - v1 is used by the SDK Updater in Tools r3 and r4.
-
-         - v2 is used by the SDK Updater in Tools r5:
-            - It introduces a new <sample> repository type. Previously samples
-              were included in the <platform> packages. Instead this package is used
-              and and the samples are installed in $SDK/samples.
-            - All repository types have a new <obsolete> node. It works as a marker
-              to indicate the package is obsolete and should not be selected by default.
-              The UI also hides these out by default.
-
-         - v3 is used by the SDK Updater in Tools r8:
-            - It introduces a new <platform-tool> repository type. Previously platform-specific
-              tools were included in the <platform> packages. Instead this package is used
-              and platform-specific tools are installed in $SDK/platform-tools
-            - There's a new element <min-platform-tools-rev> in <tool>. The tool package now
-              requires that at least some minimal version of <platform-tool> be installed.
-            - It removes the <addon> repository type, which is now in its own XML Schema.
-
-         - v4 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.
-            - <platform> element now has a mandatory <layoutlib> that indicates the API
-              and revision of that layout library for this particular platform.
-
-         - v5 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.
-            - <platform> has a new optional <abi-included> that describes the ABI of the
-              system image included in the platform, if any.
-            - New <system-image> package type, to store system images outside of <platform>s.
-            - New <source> package type.
-
-         - v6 is used by the SDK Manager in Tools r18:
-            - <extra> packages are removed. They are served only by the addon XML.
-            - <platform>, <system-image>, <source>, <tool>, <platform-tool>, <doc>
-              and <sample> get a new optional field <beta-rc> which can be used to indicate
-              the package is a Beta Release Candidate and not a final release.
-
-         - v7 is used by the SDK Manager in Tools r20:
-            - For <tool> and <platform-tool> packages, the <revision> element becomes a
-              a "full revision" element with <major>, <minor>, <micro> and <preview> sub-elements.
-            - The <beta-rc> element is no longer supported, it is replaced by
-              <revision> -> <preview> and is only for <tool> and <platform-tool> packages.
-            - <min-tools-rev> and <min-platform-tools-rev> also become a full revision element.
-
-         - v8 is used by the SDK Manager in Tools r22:
-            - It introduces the new <build-tool> repository type, which contains build-specific
-              tools that were before placed in either <tool> or <platform-tool> (e.g. ant,
-              aapt, aidl, etc.)
-            - <tool> has a new "min-build-tool" attribute.
