Dear all,
although there has not been an answer on that topic so far, we need to
find a solution for the problem, because it is essential for railML 3.1
and related "beta 2" version scheduled for end of August [1].
In particular, I already implemented the required RTM related change in
railML 3.1. The latest version of railML 3.1 is available in the railML3
SVN trunk [2]. An overview of all the changes is provided in [3].
In this overview, replacing validity attributes by new Base class
Validity to allow for multiple validity times is marked as issue number 3.
