A set of extracters for different mimetypes can be activated across AVM land. The XML extraction sample has been modified to be AVM-specific, and therefore includes the necessary config to activate the metadata extraction in AVM. git-svn-id: https://svn.alfresco.com/repos/alfresco-enterprise/alfresco/HEAD/root@6238 c4b6b30b-aa2e-2d43-bbcb-ca4b014f7261
