def lsst.pipe.drivers.utils.TractDataIdContainer.makeDataRefList	(		self,
			namespace
	)

Make self.refList from self.idList

It's difficult to make a data reference that merely points to an entire
tract: there is no data product solely at the tract level.  Instead, we
generate a list of data references for patches within the tract.
