// Performs various validation steps on the descendants of
// 'selector'. Elements that should be validated must have an
// attribute named "data-validate" which is set to a space-separated
// list of tests to perform. Additionally, the attribute
// "data-title" must be set to a human-readable name of the field
// that can be shown as part of an error message.
//
// Supported validation tests are:
// - "required": the field must be set (its .val() must not be empty)
//
// The validation will abort and return "false" as soon as
// validation routine fails.
//
// The function returns "true" if all validations succeed for all
// elements.
