I can use a version tag in a call activity to bind a bpmn element

Given:

• A process model contains a call activity
• The binding is set to versionTag and a calledElementVersionTag is provided, for example like this

  <bpmn:callActivity ...
     calledElement="simpleSubProcess"
     camunda:calledElementBinding="versionTag"
     camunda:calledElementVersionTag="my-version-tag" />
  

When:

• The call activity is executed

Then:

• The process is selected by the provided version tag.

Additionally:

• If a tenant is provided, then it should also taken into account to select the subprocess.
• The property calledElementVersionTag can be a literal or an expression.
• If there are more than one process that share the same version tag, then an exception should be thrown.
