When editing jboss-esb.xml files, if a a configuration contains a runtime property for an numeric attribute, validation errors are thrown. It would be nice to allow properties like this in numeric values of jboss-esb.xml files.

<jbr-provider host="${jboss.bind.address}"
name="dk.telenor.esb.sample.JBRChannel" protocol="http">
<jbr-bus
busid="dk.telenor.esb.sample.tdc.columbine.TestColumbineJBRBus" port="${jbr.port}"/>
</jbr-provider>
