OARIS3 — The IDL files contain vendor-specific constructs. Those should be removed.

Some of the IDL files contain the construct:

#pragma keylist ...

This annotation is specific to OpenSplice. It comes from a time before there was a standardized way to indicate DDS keys. It is not standard not supported by other DDS vendors.

With the adoption of DDS-XTYPES and later IDL4 there is now a standard @key annotation supported by the recent versions of DDS from all the vendors.

Moreover, the maintainers of OpenSplice are now focused on a new codebase (Cyclone DDS) and recommending users to migrate to it (see
https://github.com/ADLINK-IST/opensplice), and Cyclone DDS also supports the @key annotation as described in https://cyclonedds.io/content/guides/supported-idl.html.

Given all this, the #pragma keylist annotation should be removed.
