a quick follow-up question: the cache- and schema validation-integrations that you refer to, are any of those open source? If I can avoid re-inventing anything then that would be truly wonderful ;)
We may soon add some documentation on how to fuse BaseX and Voldemort. Regarding the integration of memcached and Saxon, both solutions were pretty based on a few lines of code, so it would probably take more time to cleanly extract and document them. Maybe we'll have more time for that on future (or as part of a commercial request ;).
Best, Christian
