This document defines trace semantic conventions used by the compatibility components, e.g. OpenTracing Shim layer.
Links created by the OpenTracing Shim MUST set opentracing.ref_type
with one of the accepted values, describing the direct causal relationships
between a child Span and a parent Span, as defined by
OpenTracing.
| Attribute | Type | Description | Examples | Requirement Level | Stability |
