> These are the steps to get Forrest running with Cocoon-2.1 rather than the 
> current situation which uses an old Cocoon trunk. Not everything yet works, 
> but enough to give hope. See discussion at:
>  Re: upgrade strategies for our packaged Cocoon
>  http://marc.theaimsgroup.com/?l=forrest-dev&m=116969420304386
> --------------------------
> Steps:
> Revert main/java/org/apache/forrest/util/XPathTransformer.java r111200
> Revert main/java/org/apache/forrest/util/IdGeneratorTransformer.java r111200
> Edit main/webapp/WEB-INF/cocoon.xconf
> to change version attribute to ... cocoon version="2.1"
> Move content of WEB-INF/xconf/forrest-core.xconf into WEB-INF/cocoon.xconf
> Remove the <components> wrapper.
> Build cocoon-branch-2_1_X for the blocks that we use (see our 
> etc/cocoon_upgrade) and replace the jars in lib/core
> --------------------------
> Some results:
> localhost:8888/samples/sample.html ... missing decoration
> localhost:8888/samples/sample.xml ... seems okay
> localhost:8888/samples/sample.pdf ... seems okay
> localhost:8888/index.html ... The requested resource "/index.html" could not 
> be found
> localhost:8888/index.xml ... seems okay
> localhost:8888/index.pdf ... complains about linkmap-index.xml
> localhost:8888/linkmap.html ... The requested resource "/linkmap.html" could 
> not be found
