instance.bind

You can bind operation fields to variables specified in the instance.spec property of the service that implements the operation.

<!-- The value of the domain field - a string -
    is used to select the node where the
    Sequencer service is instantiated  -->
                                
<service name="Sequencer" 
    provision="sequencer">
    <prop name="instance.spec" 
        content-type="text/x-erlang" 
        Domains="foo"><![CDATA[
#{
    domains => Domains}.
    ]]></prop>
</service>
                                
<notify name="myNotify" 
    service="Sequencer" 
    fields="domain">
    <prop name="instance.bind" 
        Domains="domain"/>
</notify>
