Attributes for the <retarget> Step

The <retarget> step has a required attribute, host, which is the target host on which the contained steps should be executed. This attribute can reference simple substitution variables.

This attribute is used by the <retarget> step, as well as by various component targeter elements. Its value is the name of a host, which can include substitution variable references. The value can also include the symbolic name / to reference the root physical host of the current execution target, or ..(/..)* to reference a parent host of the current execution target.

When a component targeter specifies a host attribute, it is semantically equivalent to enclosing the containing step in a <retarget> step.
