A string that explains a constraint when the constraint is violated. For example, without a constraint description, a parameter that has an allowed pattern of [A-Za-z0-9]+ displays the following error message when the user specifies an invalid value:

By adding a constraint description, such as must only contain letters (uppercase and lowercase) and numbers, you can display the following customized error message:

Malformed input-Parameter MyParameter must only contain uppercase and lowercase letters and numbers.
