Dear railML users,
During our railML conference in Berlin a discussion about the issue of
this thread started. (Look at the end of this posting.)

I summarized the new arguments in the appropriate Trac ticket. [1]
During the last railML conference (2013-03-06) in Berlin the use case
for "mandatory stop" was questioned.
The described scenario is very specific to the German railway
operations. In order to avoid country-specific operation rules in the
context of the more general railML data exchange, the current
implementation should be removed.
As a short-term solution, the partners may use any-Attributes instead.
An implementation following the idea of an operational stop would be
preferred to the current implementation as a "speedChange".
Any comments* appreciated.
