For this rule, add an action to set another value (ideally in a secondary data source). Use that value to conditionally enable or disable validation on the original field.

I have 2 fields that users have to enter latitude and longitude. The data type is "double, not required"(&lt;xsd:element name="PHYS_LOC_begin_latitude" nillable="true" type="xsd:double"/&gt;). I need this field to be validated but not required. I've used the "data validation" button and the field then becomes required. Is there a workaround for this? Can anyone help?
