There is no question of including DASH technology in HTML5, just means 
to control DASHed media.
What some participants of the workshop defended was the inclusion of a 
way to deal, within HTML5, with various options offered by DASH, such as 
choice of bit-rate, audio, subtitles, as well as support for trick modes 
(a.k.a. VCR-like controls).
One possible solution is to add element/attribute syntax around the 
video object to allow that kind of control. Another solution is to add 
script APIs.
Best regards
