For those who are interested: I have added a wiki page with a brief list of steps explaining how to test Doxia-1.1-SNAPSHOT and the sandbox pdf plugin [1].
Currently you have to build and use a local version of Maven 2.1.0-M2-SNAPSHOT, but we plan to switch 2.1.0-M3 over to Doxia-1.1 as soon as M2 is released, so early feedback and volunteer testers are very welcome!
Cheers, -Lukas[1] http://docs.codehaus.org/display/DOXIA/Testing+Doxia-1.1-SNAPSHOT+and+the+pdf+plugin
