 ## Substream Constraints
 
 Mux Senders create IS-04 Flow objects for each subflow included in the mux Flow.
-The mux Flow links to each subflow object using the `parents` construct described in [AMWA IS-04](https://specs.amwa.tv/is-04/)
+The mux Flow links to each subflow object using the IS-04 [`parents`](https://specs.amwa.tv/is-04/latest/docs/Data_Model_-_Identifier_Mapping.html#source-and-flow-representation) attribute.
