Harmonize 'electrification' between IS and RS
There are some types and attributes for electrification systems in Infrastructure and Rollingstock parts. They define quite the same with different structures.
some hints:
- voltage
- frequency
- catenary/third rail
- rack Traction
New base types may be provided by railwayBaseTypes.xsd
if needed.
isolatedSection
should be some own trackElement
because of its positioning and different kinds.
vMax
may be deleted in tElectrificationChange
, it should be defined with speedChange
element.
Don't implement default values in schema attributes!
