Hello, I'm Karl 334. I wanted to let you know that one or more of your recent contributions&#32;to Unified Modeling Language have been undone because they did not appear constructive. If you would like to experiment, please use your sandbox. If you have any questions, you can ask for assistance at the Teahouse or the Help desk. Thanks.
