Dear all,
a change to the formation attributes was discussed at the last
coordinator meeting. The aim is to not allow values such as speed="0"
and length="0" for the element <formation>.
A TRAC ticket (#269, http://trac.railml.org/ticket/269) was created for
this change for the upcoming railML 2.3 version. Please provide
feedback/concerns in the forum till the end of October.
Best regards,
Philip

Remark on weights:
This is already clearly described in the wiki. The only definition I could find
in the www confirms this.
Gross/brutto weight (the total weight) = net weight (the weight of the goods) +
tare weight (the weight of the empty container)
Best regards,
