Review feedback: Question: Is Trailer a Vehicle ?

EDIT 2023-10-26

This issue was originally opened via e-mail, with a simple question (text below). The answer for that question is in this comment #671 (comment 51743)

However, OSC 1.x also had a feature request to add trailers (see 1.x#489). Therefore, we used this issue to make a draft of how a trailer could be implemented also in 2.x.

Now, in this issue we want to:

• Decide if we want to include trailers in 2.1 release
• Finalize the data model for the trailer and corresponding actions
• Add the new trailer content to the OSC 2.x document
