Required Controls and Validation

 controls may be marked as required or optional by setting the control's required property in edit mode. Controls that are generated from an uploaded schema will automatically be designated as required or optional depending on the schema (for example, whether the control is required based on the minOccurs value). Validation for controls you generate from schema elements depends on the element’s XSD type and other schema-specific information.

1. Apply patterns to a control - Like other control properties, the pattern property will not need to be redone when you upgrade .
2. Modify the built-in values in the types.xsd file. Be aware that if you modify the types.xsd file, you will have to make this change each time you perform a  upgrade or apply a  patch.

If you are using  Online, you will not have access to types.xsd. Both cloud and in-house customers, can override the pattern in the phone control by setting its pattern property. You can only restrict a built-in pattern (such as the phone control) but not change the pattern via the pattern property. For example you can add the pattern 203-\d{3}-\d{4}.  Now all phone numbers must start with area code 203.

A pattern such as ##-####-#### or ####-###-### is not a simple restriction. To impose validation against this pattern you must start with a Text control rather than a Phone control
