Unable to retrieve a document attached in a SOAP MTOM/XOP message sended by WSO2 library

Using a axis2 Web Service, when trying to retrieve a document attached in a SOAP MTOM/XOP message builded using WSO2 php library get this error:

org.apache.axiom.om.OMException: javax.xml.stream.XMLStreamException: Expected xop:Include as the sole child of an element information item (see section 3.2 of http://www.w3.org/TR/xop10/)

This is due to the fact that the element (<xdsb:Document id="Document01"> </xdsb:Document>) (OMElement obtained after axis2 processing) that should contains the base64 value of document, is empty. But observing the same message sniffed from wireshark (protocol analyzer) it seems that the Document is present.

I am worried about which library is the guilty for this problem: "WSO2" or "axis2"?

I try to send (in SOAP MTOM/XOP) a similar message with another client using AXIS2 library and I retrieve CORRECTLY the document attached.
