If I want to migrate (/subsystem=jacorb:migrate() JacORB subsystem which contains non-default values of initializers element then that element is not transferred at all.

        <subsystem xmlns="urn:jboss:domain:jacorb:1.4">
            <orb socket-binding="jacorb" ssl-socket-binding="jacorb-ssl">
                <initializers security="off" transactions="off"/>
            </orb>
        </subsystem>

is transfered to

        <subsystem xmlns="urn:jboss:domain:iiop-openjdk:1.0">
            <orb ssl-socket-binding="jacorb-ssl" socket-binding="jacorb"/>
        </subsystem>

Security element
jacorb possible values: identity, on, off, client
openjdk: identity, client, none
Transactions element
jacorb: on, off, spec
openjdk: full, none, spec

I'm not sure how the conversion should look like exactly but e.g. I expect that off could be transfered to none etc.
