Identifier. The resource name of the tag in URL format where tag ID is a system-generated identifier.
Note: The tag itself might not be stored in the location specified in its name. It takes the form projects/{project}/locations/{location}/entryGroups/{entrygroup}/entries/{entries}/tags/{tag}.
Names of fields whose values to overwrite on a tag. Currently, a tag has the only modifiable field with the name fields.
In general, if this parameter is absent or empty, all modifiable fields are overwritten. If such fields are non-required and omitted in the request body, their values are emptied.
This is a comma-separated list of fully qualified names of fields. Example: "user.displayName,photo".
