Dear all,

there are cases when different signals, e.g. main and shunting or main and distant, are mounted on the same mast. In
such cases they might have slightly different functionality from the interlocking perspective. In railML interlocking
they would represented by different elements <signalIL>.

In order to mark the relation I suggest to add a boolean attribute @onSameMast to <signalIL>, which is set "true" for
shunting or distant signals, if they are mounted on the same mast.

For a more destinctive relation it might be better to use an alternative approach instead: new child <onSameMastWith> of
type EntityILref, i.e. with reference to the other <signalIL> [0..*] mounted on the same mast.

Please, give me your opinion, which solution would suit your needs.
