As blogged elsewhere, we now have some <m> components of <hyph> which break down into multiple morphemes; we're expressing these using @corresp with multiple values, instead of @sameAs with one. I've now written some basic handling for that situation. In the process, I had to migrate the stylesheet from XSLT 1.0 to 2.0. The site is a mix of both. It really needs to be remodelled using a new Cocoon/eXist stack. I'll do that as soon as we have the new Tomcat box up and running.
