Currently the different views of an issue are done through JSP. We should make view of an issue pluggable so that we can use velocity (through the plugin system). We should also allow for other content types to be created (eg application/pdf for a PDF version of an issue). Currently the XML version is linked up the top - in the future, other versions would be linked (with the default view being the one displayed normally). One other implication is to use the same (similar) view technology for the differing views on the issue navigator. You could reuse the 'full content view' (which should be the printable view of an issue repeated), as well as the XML view. A CSV view may also be useful, although less useful on an individual issue.
