View source for Constraint-based alerts

One issue to address pertains to the proposal to have a [[Constraint-based_Alert]] (see also [[MIP_Names,_Types,_Etc.]]).  If more than one constraint is expressed, then the alert should be based on which constraint was violated.  A definition would be required for what to do if multiple constraints are violated. The alert messages could be concatenated with a separating space, linefeed or configurable separator.
