Confusion between vendor and tenant in tracestate keys

§ 3.3.1.3.1 Key:

Vendors SHOULD set the tenant ID at the beginning of the key. For example,
fw529a3039@dt - fw529a3039 is a tenant ID and @dt is a vendor name.

The example key seems to have the tenant ID at the end, not the beginning. Or am I missing something?

Thank you! Also discussed we need to change dt to smething obviously meaningless as part of this errata

This user is confused about the difference between "tenant" and "vendor." This is actually not an error. In the key fw529a3039@dt, the vendor is dt but the tenant is fw529a3039. The tenant ID in this case is at the beginning of the key.

I would suggest wording like this:

In a distributed application where different components may be traced by different instances of the same multi-tenant tracing system, the system SHOULD keep the system ID at the end of the key. For example, 001@xyz - 001 is a tenant ID and xyz is a vendor name.
