DASH webm ondemand profile does not conform to specification

ffmpeg generates DASH webm manifests with the following profile: urn:webm:dash:profile:webm-on-demand:2012 as hardcoded in libavformat/webmdashenc.c.

This file references the documentation at

That very documentation however says the profile should be: urn:mpeg:dash:profile:webm-on-demand:2012.
Note the difference in second word, webm vs mpeg.

Why does ffmpeg contradicts the documentation it is apparently based on?
I believe the profile should be as specified in the spec, but at the same changing fffmpeg behavior is likely to be a serious breaking change as clients might rely on ffmpeg version of the profile.
