Since jEdit comes with an edit mode for Zope Page Templates (zpt), I think it would be natural for the XML plugin to support such files - such as automatic closing tags, block level outline, etc. I've done this by extracting XML.props from the plugin, adding the line mode.zpt.sidekick.parser=html, then updating the jar file. This doesn't do validation, but treats the zpt file like an html one, without having to change my edit mode to html. Could this line be included in future versions of the plugin?
