 In Sentry, we have two options for how to treat span events. First, we can add them as breadcrumbs to the transaction the span belongs to. Second, we can create an artificial "point-in-time" span (a span with 0 duration), and add it to the span tree. TODO on what approach we take here.
 
-In the special case that the span event is an exception span, [where the `name` of the span event is `exception`](https://opentelemetry.io/docs/reference/specification/trace/semantic_conventions/exceptions/), we also have the possibility of generating a Sentry error from an exception. In this case, we can create this [exception based on the attributes of an event](https://opentelemetry.io/docs/reference/specification/trace/semantic_conventions/exceptions/#attributes), which include the error message and stacktrace. This exception can also inherit all other attributes of the span event + span as tags on the event.

This is addressed by Step 7, where you add `generateSentryErrorsFromOtelSpan` to the `SpanProcessor` pipeline.
 
 In the OpenTelemetry Sentry exporter, we've used this [strategy to generate Sentry errors](https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/8eda2f80b6dbd5aea03ca699c3ad1454714156d0/exporter/sentryexporter/sentry_exporter.go#L169-L196).
