> When the master HC is transforming the domain-level configuration model in order to provide it to a registering slave host, it should not bother transforming resources that are going to be ignored once they arrive at the slave.
> To facilitate this, the slave should include ignored-resource data as part of the "host-info" ModelNode it passes to the master when it initiates registration.
> One thing this (partly) allows is registration failure on the master if it detects the presence of unignored resources that the a slave running any earlier version cannot understand. The master cannot *always* fail in this situation, since the slave may be configured to ignore the offending resource. Providing the ignored-resource data allows the master to make a more informed decision.
> Note: I say "(partly) allows" above because the master cannot "eagerly fail" if the registering slave is running a version that precedes the completion of this task.
