No recalculate/refresh occurs between xf:submit::DOMActivate, and xforms-submit

In some cases, a constraint does not apply to all nodes targeted with an xf:bind. The attached form demonstrates one such case. In this form, entering data such as "hello" into the field should prevent the form from being submitted (as it is an invalid value). Note that this example form will try to save data into a sibling file named "foo.xml".
