Thanks for review. Yes we might integrate another USE but am preferring slight difference in font styles for the displayed text.
Tweaked description text of TouchSensor to match sense of user message. Also added screenshot.

Thanks. "Press and hold" works well.
The UserMessage Shape at the bottom could use the TextAppearance
Appearance to avoid repetition and save a few bytes.

Meanwhile found a setting in XMLSpy that aligns handling of whitespace with X3D Canonical Form, which is what we use in version control and diffing and XML security and X3D Binary. Pretty simple adjustment: use 2 spaces instead of tabs for indentation.
