I've now finished converting all the original templates from the Cocoon app into modern XSLT 3, with the exception of the stuff relating to the image browser and similar special pages. There are still some page-level modules that need to be done, such as rendering the abstracts and the correspondence headers, but we're close. The output is a long way from valid, though, so I'm now going through the process of debugging and fixing things like nested links. 480 minutes, today and yesterday.
