How to deal with UUIDs

Background:

railML3.2 has id attribute as union of XML id and UUID. This creates issues for type recognition, interpretation during import, XML validation and code generation.

Proposed solution:

create a new UUID attribute

  • Remove UUIDs from the tID and tRef types.
  • Create a new entry in Registers.xml to include UUID as a designator.
  • Ensure that all relevant entities offer <designator>
  • Avoid required elements and attributes as siblings to <designator>, to enable elements that are empty husks only containing id and <designator>
