The additionalParameter.yaml file in the OGC API Processes repository (core/openapi/schemas/additionalParameter.yaml, 1.0.0-maintenance branch) is not a valid OpenAPI Schema Object and fails Spectral/OAS validation with the error docs-parameter-examples-or-schema: No example or schema provided. The file currently contains only a description field and does not define a type, properties, $ref, or an example, all of which are required for a valid schema. This breaks strict OpenAPI validation.
