How to retrieve inputstream from StaxSource when using Provider API

Hi,
I need to do stream large messages that will be passed from the client to the server side - so decided to go with the provider API. However on the server side we receive a StaxSource object - and it is not possible to retrieve a stream from that object. I had to do the following in my code - but it doesnt seem like the right solution since i do not want to write out all the binary data in memory in the ByteOutputStream... Does Metro provide some way of going about it - since the whole purpose of Provider API is to enable us to handle large messages --
ByteArrayOutputStream bos = new ByteArrayOutputStream();
StreamResult streamResult = new StreamResult(bos);
Transformer trans = TransformerFactory.newInstance().newTransformer();
trans.transform(inSource, streamResult);
bos.close();
ByteArrayInputStream in = new ByteArrayInputStream(bos.toByteArray());
thanks.

Are you aware of this:
