Thank you.

There are some attributes in that group which make no sense for speed
profiles: regularBrakeMass, emergencyBrakeMass, max/meanDeceleration. They
apply to vehicles and trains only. You have no mass at a speed profile.
There may be (theoretically) a minimum necessary deceleration
(representing the minimum brake percentage in a physical clear manner) but
no max or mean deceleration.

I suggest to reduce the attributes to the real necessary
minimumBrakePercentage, brakeType, and airBrakeApplicationPosition.

So why don't you move it? We have already discussed it on 29.06.2012 and
26.04.2012. Already then it was written: "So, I would prefer to add the
above named triplet as attributes of a speed change: They are valid until
the next speed change with such attributes."

Best regards,
Dirk.
