switch anthropicDocumentBlockParamContent2.Type {
	case components.AnthropicDocumentBlockParamContent2TypeStr:
		// anthropicDocumentBlockParamContent2.Str is populated
	case components.AnthropicDocumentBlockParamContent2TypeArrayOfAnthropicDocumentBlockParamContent1:
		// anthropicDocumentBlockParamContent2.ArrayOfAnthropicDocumentBlockParamContent1 is populated
}
```
