Dear Heidrun,
I took your topic with me into the "2nd railML 3.1 Workshop" in Berlin
last week.
Concluding the discussion the proposal has been seen sceptical from most
of the workshop participants: Although some lines "can be saved" in the
export file, it was highlighted that new problems and inconsistencies
may arise from the shortened topology location. In particular, listing
references in the attribute @netElementRefList has been criticized, also
because of resulting validation problems.
However, what about the rest of the community? @all: Do you have any
opinion about the proposal from Heidrun? Any feedback is highly
appreciated...
Best regards
Christian
