Are the advanced characteristic options required?

The advanced characteristics options—available only to text type characteristics—are not required. You may use text type characteristics without using the advanced options. The two advanced options are input mask and validator. An input mask creates a template to guide users as they enter values for a characteristic. It is a form of light data validation. For example, if you specify the input mask 00/00/0000, then users will be presented with the following template when they are entering values for the characteristic : "__/__/____". In this case, users will simply have to fill in the blanks between the separators. A validator is used to strictly enforce the format of data users can enter in a field. If you specify a validator for a characteristic, then users will have to conform to the format when entering values for the characteristic. Values which do not conform will not be accepted.
