What i am doing in short is: Implementing a transformer (similar to cinclue) only that for ich request to another source i start thread, which process the source. The transformer continues to go through the sax events. At the endDocument method, the transformer waits for all launched threads and serializa their output into single stream of SAX events.
Take a look at IncludeTransformer in the scratchpad - does exactly the same.
