Mac OS: Open Transport Compatibility

A general statement has been used to describe Mac OS/Open Transport compatibility:

Open Transport is supported on system software versions 7.1, 7.1.1, 7.1.2, 7.5.3, 7.5.5 or later. System software version 7.5.3 or later is recommended. No other system software versions are supported.

However, the statement does not specifically state compatibility with 7.6, 7.6.1, Mac OS 8 and 8.1.

Specifically, what are the supported versions of Open Transport with Mac OS 8.1 - what are the supported methods for installation?

Also, if OT 1.3 is supported by 7.1, what is the supported method for installation? Attempting to install OT 1.3 will result in the error that OT must be installed via the 8.1 installer.
This is really fairly simple:

1) Open Transport 1.2 is available and supported only on Mac OS 8.

2) Open Transport 1.3 and 1.3.1 are available and supported only on Mac OS 8.1.

3) Previous versions of OT are supported on Systems running 7.1 or greater. Although you could run the OT 1.2 standalone installer from Mac OS 8.0 disk without having Mac OS 8.0 installed it is not a supported configuration. OT 1.3 and 1.3.1 will only install on a Mac OS 8.1 based system.
