This breaks down into two further questions:
emsg
events?emsg
events, what event message schemas are supported?Is capability detection for the latter needed? If an implementation supports surfacing DASH emsg
events, can we assume it will expose all such events, regardless of event schema?

A native DASH player would not expose events that are targeted at the DASH player such as MPD reload events.
I don't think there's a need for capability detection for that case, as an implementation that can handle one emsg
schema could equally handle any schema. In the context of an MSE based player (as native DASH playback is currently not defined by any web specs), is there a need for an API to subscribe by scheme id/value?
Question from @wolenetz at the TPAC 2020 meeting on DataCue: Does there need to be feature detection so that web applications can discover which types of UA-generated events are exposed via DataCue?
A suggestion is to add this to Media Capabilities.
