"A user agent recognises and supports data from a MPEG DASH media resource as
being equivalent to a HTML track based on the AdaptationSet or ContentComponent
mimeType:"
It is unclear how many tracks should be created: 1 per AS or 1 per
Representation, or 1 per ContentComponent. Also, it is not clear which AS
should be exposed ? All including those for which the mime type is not
supported? 

Please rephrase using normative statements such as:
"User agents shall expose HTML tracks for all AdaptationSet elements in an MPD.
For  AdaptationSets for which the MIME type is not supported, it shall expose
the associated tracks as HTML TextTracks. For AdaptationSets for which the MIME
Type is supported, it shall expose AdaptationSet whose MIME main type is
"video" (resp. "audio") as HTML VideoTracks (resp. AudioTracks) and as
TextTracks for all others. In a given AdaptationSet, UA shall expose all
Representations as an HTML Track. If representations carry multiplexed streams,
the UA shall expose each ContentComponent as an HTML Track."
