One of frevvo's most powerful and useful features is its ability to automatically ensure that any submitted form generates a set of XML documents that are valid with respect to their corresponding XML schemas. frevvo does this by:
...
On form load, required controls that do not contain valid values have a visual indicator. For example, an invalid control has a yellowish background when a required field is missing a value, and additionally, a warning icon when a control (either required or not) contains an invalid value.
...
Apply patterns to a control - Like other control properties, the pattern property will not need to be redone when you upgrade frevvo.
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 frevvo upgrade or apply a frevvo patch.
...
If you are using frevvo Online, you will not have access to types.xsd. Both Cloud and On Premise 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.

The Pattern property will not need to be redone when you upgrade frevvo. |
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
