-If the unit of code has a version then the instrumentation scope is defined by
-the (name,version) pair otherwise the version is omitted and only the name is
-used. The name or (name,version) pair uniquely identify the logical unit of the
-code that emits the telemetry. A typical approach to ensure uniqueness is to use
-fully qualified name of the emitting code (e.g. fully qualified library name or
-fully qualified class name).
+The instrumentation scope is defined by the
+(name,version,schema_url,attributes) tuple where version, schema_url, and

 The instrumentation scope is used to obtain a

+The instrumentation scope's optional Schema URL identifies the [Telemetry
+Schema](schemas/README.md) that the instrumentation's emitted
+telemetry conforms to.

 The instrumentation scope may have zero or more additional attributes that provide
 additional information about the scope. For example for a scope that specifies an
 instrumentation library an additional attribute may be recorded to denote the URL of the
