Environment Specification

Product registration applies to software products operating in a specific hardware or hardware/software environment.

A product may be registered in all members of a binary-compatible family of products on the basis of a single test report.

Answer the questions for each binary-compatible family. Alternatively, provide the answers in the Appendix at the end of this document or if lengthy provide a separate external html file to The Open Group that can be linked into the Appendix.
