    See also [Allow Metadata Save Operations to Complete with Returned Warnings](https://developer.salesforce.com/docs/atlas.en-us.api_tooling.meta/api_tooling/tooling_metadata_save_warning.htm "When a metadata save operation generates warnings, the default behavior of Tooling API is to fail the operation without returning the warnings. For objects in both the Tooling API and Metadata API WSDLs, you can indicate that you want error-free save operations to complete successfully, returning any warnings.")
