8-1 does not prevent it.
Even fixedLength encoding forsees 2 bytes for the transmission of enumeration value - allowing a range of: -32768 to 32767.

GOOSE subscriber, including Fixed length.

This could really complicate the MMS mapping.
8-1 says "the MMS data type shall be the minimum size required to contain the maximum standardized value".
Currently, all Enums map to an 8-bit signed integer.
But if one attribute exceeds 127, it will need a different MMS data type than all other Enums. This can be done, but users will need to know the "maximum standardized value" for each Enum.

To respond to John:
"but users will need to know the "maximum standardized value" for each Enum"

It is not only about maximum standardized value, but minimum extended value. Users can check the EnumerationType from SCL since SCL Ed1.

The issue is not only for the scope of fixed-length GOOSE tests, but also for BER-encoded GOOSE tests.
Additionally, the test procedure shall indicate that the EnumType in the SCD is indicating ord values that are negative, or bigger than 129,...

I wouldn't make the test conditional ENS can be subscribed.
The ENS using values outside the INT8 range, could be in a DataSet with bolean; those boolean are indeed subscribed (application) - and ping-ponged.
When a subscriber cannot subscribe to a type, I think it is meant: the application cannot receive it, but the communication can. Otherwise it is difficut to shre and configure dataSet based on what the subscriber is allowing. Am I wrong?
