**Parameters:**

* `component_provider` - The `ComponentProvider`.
* `type` - The type of plugin interface it provides (e.g. SpanExporter, Sampler,
etc).
* `type` - The type of plugin interface it provides.
* `name` - The name used to identify the type of component. This is used
in [configuration model](./data-model.md) to specify that the
corresponding `component_provider` is to provide the component.

The `type` and `name` comprise a unique key. Register MUST return an error if it
is called multiple times with the same `type` and `name` combination.

SDKs SHOULD represent `type` in a manner that is idiomatic for their language.
For example, a class literal, an enumeration, or similar.
See [supported SDK extension plugins](#sdk-extension-components) for the set of
supported `type` values.
