All of the LandXML files I have seen use the <Alignment>.staStart attribute to indicate the starting station.

There is also an attribute "StaStart" for all elements in an alignment such as circcurve, line, etc.. We are now not sure what the meaning of the alignment StaStart should be and how to handle it. Which stationing values are the relevant ones? Do we have to care about the alignment staStart if we import or export alignment data in our applications?
