Returns the Host node corresponding to the given node. The given node can be any directly discovered data node, or a Software Instance or Business Application Instance. If more than one Host is related to the given node (for example a Business Application Instance spread across multiple Hosts), an arbitrary one of the Hosts is returned.
model.host function, with a lower-case "h" has an unfortunate clash with
model.Host with an upper-case "H", which creates or updates an existing Host node. Be sure to use
model.host with correct capitalisation. Since patterns are not normally responsible for maintaining Host nodes, the system issues a warning if
model.Host is used.
