Enhance with further states

Description

Most infrastructure elements already have a child element , which allows to mark them as being not available for operation via the boolean attribute @disabled.

The task is to think about enhancement of this element to cover a wider variety of states regarding the availability of these infrastructure elements.

Proposed solution in railML 2.4

Fuse implementation of with already existing enumeration attribute @status, which provides the following states for the OCP:

• planned
• operational (default value)
• disabled
• closed

In parallel to adding the attribute @status, the existing boolean attribute @disabled need to be set, because it is a mandatory attribute. Therefore, @disabled cannot be marked DEPRECATED although it does not provide any additional information to what is expressed with the new attribute @status.

The following example describes a level crossing that is currently not available for operation:

<levelCrossing ...>
  <states>
    <state status="disabled" disabled="true"/>
  </states>
</levelCrossing>

Further, the OCP status information is moved inside the new child element . In parallel, the existing attribute @status is marked DEPRECATED.

Example for the OCP:

<ocp ...>
  <propOther ...>
    <states>
      <state status="planned"/>
    </states>
  </propOther>
</ocp>

Last, but not least, it was suggested to add another status enumeration value indicating that something is intended to be built, but not yet in a real planning status. In fact, a "concept" is described and therefore, it is suggested to name the new enumeration value "conceptual".
