New element for mileage change modelling
Description
The mileage cange shall be modelled explicitly with a new funtional infrastructure element. This solution shall replace / complement the approach of RTM based <linearPositioningSystem> and its anchor points.
Background
The request resulted from discussions in the railML ETCS use case working group.

Proposed solution railML 3.2
New container element <mileageChanges> shall be added inside <functionalInfrastructure>. It includes a list of <mileageChange> elements.
The <mileageChange> has an attribute @type with values "gap", "overlap".
The <mileageChange> references child elements <spotLocation> via attributes @from and @to.
The <mileageChange> has two child elements <spotLocation>. One provides the link to the "incoming" mileage and the other one provides the link to the "outgoing" mileage.
