Retaining a DTMManager will indeed retain the documents it has cached, which is not what you want in this case.
To solve this, I believe you can simply discard the Transformer after use, and obtain a new one from the TransformerFactory. Since the DTMManager is associated with the Transformer, this should result in flushing the cache and starting a new one. ______________________________________ "...
