A transformer provides well defined function signatures per each communication relation

(port based and signal based), which is marked for transformation. The function

signature depends on the transmitted data elements (Client/Server operation signature

or Sender/Receiver interface signature) only. The output of a transformer will be always

a linear byte array.-Both data transformation and communication itself are very extensive fields and can

get quite complex because a lot of use cases and scenarios are theoretically possible.

Because these have a big impact on the functionality of transformer (especially in the

RTE), this diversity makes it necessary to impose a few restrictions and assumptions

to the transformers.
