In the above discussion, we agreed on the opinion that the attribute
'isoCountryCode' is not needed: Many lines in border regions include
tracks in two or more countries. To avoid additional cuts of the line,
the attribute 'isoCountryCode' is deleted. However, the line is uniquely
defined by the 'infrastructureManagerCode' and the 'code' given by the
infrastructure manager.
