Deletes a file tag.
This method deletes the file tag identified by TagId or TagName from the file, directory, or alternate stream specified by FileName.
The value passed for FileName must be a vault-local absolute path.
To delete a raw file tag, pass its Id for TagId and pass empty string for TagName. To delete a typed file tag, pass its name for TagName and pass 0 for TagId. If values are provided for both TagId and TagName, this method throws an exception.
Please refer to the File Tags topic for more information.
Note: This method can only be called when Active is true, and cannot be called within events.
