Here is my proposal from Feb 4th:

Ideally we'd want a rangeOfInteger(0:MAX) value to provide minimum and maximum lengths - not sure how much trouble we'd cause by extending that attribute to "integer(0:MAX) | rangeOfInteger(0:MAX)", but IMHO that would be the ideal outcome.

alternately we can add a "job-password-minimum-length integer(0:255)" attribute to specify the minimum length of a "job-password" value separately.
