You can reference particular fields in a separate form (rather than a complete form) through the use of the <FormRef> element.
Use the <FormRef> element to include another form from within an external form. The following example calls the form named MissingFields.
<FormRef name=’MissingFields’/> <FieldRef name=’AuthenticationAnswers’/> <FieldRef name=’AccountInformation’/> <Field name=’waveset.backgroundSave’> <Display class=’Hidden’/> </Field>
