In many complex CI/CDs the workers are categorized by other attributes, such as the platform they run (ubuntu, windows) the tooling they have installed (java, go) or other attributes.

I lean towards leaving this attribute open (without pre-defined values). Also consider class as an alternative name to reflect its intention to group the workers into categories.

**[1] `error.type`:** The `error.type` SHOULD be predictable, and SHOULD have low cardinality.

When `error.type` is set to a type (e.g., an exception type), its
canonical class name identifying the type within the artifact SHOULD be used.

Instrumentations SHOULD document the list of errors they report.

The cardinality of `error.type` within one instrumentation library SHOULD be low.
Telemetry consumers that aggregate data from multiple instrumentation libraries and applications
should be prepared for `error.type` to have high cardinality at query time when no
additional filters are applied.

If the operation has completed successfully, instrumentations SHOULD NOT set `error.type`.

If a specific domain defines its own set of error identifiers (such as HTTP or gRPC status codes),
it's RECOMMENDED to:

- Use a domain-specific attribute
- Set `error.type` to capture all errors, regardless of whether they are defined within the domain-specific set or not.

---

`error.type` has the following list of well-known values. If one of them applies, then the respective value MUST be used; otherwise, a custom value MAY be used.

| Value | Description | Stability |
|---|---|---|
| `_OTHER` | A fallback error value to be used when the instrumentation doesn't define a custom value. | ![Stable](https://img.shields.io/badge/-stable-lightgreen) |
