Description copied from interface: Stage
Called as part of executing a pipeline.

Parameters:
store - The store from which the authorities were retrieved.
xrd - A XRD as it currently looks like on the pipeline. The stage is free to modify and return it in any way.
segment - The XRI segment that resolves to the XRD being processed.
parentAuthority - The parent authority, i.e. the authority describing the XRD.
subSegmentName - The name of the subsegment that connects the two authorities.
authority - The authority, i.e. the authority described by the XRD.
isCreate - Whether this stage is execute as part of a CREATE pipeline.
Returns:
