If you are using JAXB 2.0, this is most easily done by using StAX. You
invoke StAX directly to write <policies>, then you pass that StAX writer
and marshal a policy object individually. You then conclude again by
writing </policies> by using the StAX writer directly. I believe there's
a sample bundled with the distribution package that does this.
With JAXB 1.0, you can still do this, but JAXB 1.0 marshaller doesn't
take StAX writer directly, so you need an adapter to bridge them
together. Look at
http://stax-utils.dev.java.net/ and use its
ContentHandler->XMLStreamWriter adapter to do this.
