Gang - Both MyFaces and Mojarra currently assume/require the file extension ".xhtml" for composite component resources. This seems overly restrictive. Composite component authors should be able to use other file extensions - eg. ".view.xml", or, as we would like to do here: ".jsf". What do folks think about introducing spec language that requires the JSF implementations to check for composite component resources under any extensions specified via the "javax.faces.FACELETS_VIEW_MAPPINGS" context parameter? Or, if we start looking into jar-specific configuration, it might be interesting to allow such extensions to be specified on a per-resource library basis. Thoughts? Andy
