Enabling experimental semconvs
******************************

Set the environment variable `OTEL_SEMCONV_STABILITY_OPT_IN` to `gen_ai_latest_experimental` to
emit the latest experimental version of GenAI conventions and to not emit the ones at v1.36.0 or prior.

Enabling message content
*************************

Message content such as the contents of the prompt and response
are not captured by default. To capture message content as log events, set the environment variable
`OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT` to `true`.

If `OTEL_SEMCONV_STABILITY_OPT_IN` is set to `gen_ai_latest_experimental` then `OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT`
must instead be one of `SPAN_AND_EVENT`, `NO_CONTENT`, `EVENT_ONLY` or `SPAN_ONLY`. This controls whether message content
is captured in spans, events, or neither.
