Custom Policy steps in OWSM

Question

I am currenly implementing an integration systems between our systems and a third party system. There is a requirement for all messages sent across the interface to be acknowldeged by the other system. The transactions are synchronous so we have hand off approach where the receiving system must acknowledge message receipt by sending a synchronous response message back. This acknowledgement message will contain a boolean flag that either says true or false depending on whether they are receiving or rejecting the message. Messages could be rejected because they have an invalid digital certificate or failed message integrity. Is it possible to create custom policy step in the OWSM that allows me to send these acknoledgement messages. the message structure will contain only 3 elements:
successfulDelivery (boolean)
RejectedCode (Rejection ErrorCode)
RejectedReason (Rejected Error Reason)
Can any one help? I am still new to the OWSM.

Here's an example on how to add a custom SOAP header to the request message inside a custom step.
public IResult execute(IMessageContext messageContext) throws Fault {
MessageContext msgCtxt = (MessageContext) messageContext;
SOAPEnvelope senv = msgCtxt.getRequest().getAxisMessage().getSOAPEnvelope();
((org.apache.axis.message.SOAPEnvelope)senv).setDirty(true);
Name header = factory.createName("CustomHeader", "http://foo.com/custom/header");
SOAPHeaderElement headerElement = senv.getHeader().addHeaderElement(header);
headerElement.addTextNode("My custom header data");
OWSM uses AXIS implementation internally to represent the SOAP message.
