Werner, Hmmm... Take a look at my reply to post "Export all items in namespace" from Sunil Abraham on 22 March. I posted a code snippet that does this for a project.
But on the other hand you could take a look at UMLanji. This tool from George James Software allows you to export your class definitions to XMI and from there you can load it into a UML tool (like Gentleware's Poseidon) and visualize your class model. I find it to be highly useable :) Now I'm not sure if the same is true about SVG, but I once tried to do something like you intend with XSLT but converting to XMI and found out the XMI DTD is 12kb long... Definitely not something to do on a rainy day. HTH, Ram�n
