AWS AWSCloudFormation medium security documentation change
Summary
Renamed and updated documentation for tag properties in DirectoryService SimpleAD. Added validation constraints for tag keys (cannot use 'aws:' prefix, length 1-128) and values (length 0-256).
Security assessment
Added explicit security constraint prohibiting 'aws:' prefix in tag keys, which prevents overwriting AWS-internal tags and maintains tag security boundaries. Also added length validation to prevent potential abuse through excessively long tags.
