Compatibility with different PRC format versions

HOOPS Exchange provides forward and backward compatibility with other PRC format versions:

Forward compatibility: The HOOPS Exchange libraries are designed to avoid failing if it reads PRC documents that conform to future releases of the PRC format. It does so by ignoring any information it does not understand.

Backward compatibility: In a major release, the HOOPS Exchange support for PRC is backward compatible. Each new version of the software can read PRC files that conform to an earlier PRC format version.
