## Build notes

### Skip the `dotnet` namespace

The [`dotnet` namespace is added in
`v1.28.0`](https://github.com/open-telemetry/semantic-conventions/tree/v1.28.0/model/dotnet).
None of the semantic conventions for this namespace are generated.

### Required semantic convention changes

Related to https://github.com/open-telemetry/weaver/issues/584, this was
not generated with a direct copy of the [semantic-conventions
repository](https://github.com/open-telemetry/semantic-conventions)
checked-out at `v1.28.0`.

The latest (v0.12.0) version of `weaver` does not work with that version
of semantic-conventions. The semantic-conventions repository was updated
using the following command first:

```
$ rm model/{telemetry/resources-experimental.yaml,service/resources-experimental.yaml,feature-flag/events.yaml}
```

This removes name conflicts. These name conflicts are for things we are
not generating, but the still block the generation tooling when it first
validates the semantic-conventions.
