The <feed> element allows you to manage and reference different qualities and resolutions for the parent <track>.
The vuid attribute indicates the version of the <feed>.
<span> elements within a <feed>must all contain the same type of media, (as defined by the media handler used by the Gateway.)
<feeds currentVersion="v2"> <feed vuid="v1" uid="f1">...
