determining, by a computing device, a second element that has been previously resolved in a first resolution of a first element during playback of a media presentation, wherein the second element is associated with a value in a manifest presentation description for the media presentation being played, wherein:
a descriptor is used to identify elements in the manifest presentation description that should be re-resolved as a group of elements after the first resolution of the first element,
the value is associated with the descriptor to indicate the second element of the manifest presentation description is part of the group of elements that have the descriptor and value, and
the descriptor and value association is unique in the manifest presentation description to represent re-resolution of the group of elements for the computing device;
