Since MD15.5.
When constraints and validation rules from active validation suites are broken the tool flags errors in the model "actively" with a coloured validation error box around a problematic element's symbol (the colour will depend on the severity level, a warning is yellow), and with a little red cross in the containment browser, and offers possible fixes
