The 3GPP TS 26.234 was used as the baseline for DASH in July of last year.
So it should be compatible because the just use a structure with
MPD->Period->Representation->SegmentInfo->(InitSegment, URL) as I know, and
with DASH it's possible to build such a structure. 

The general streaming flow is the same as I know. Both request at first a
MPD and then the download the segments that correspond to the current
bandwidth and the capabilities of the client.

Sorry but I thought that this is the right place for submitting new source
