The recalculate element
This action causes the default processing of xforms-recalculate to happen, bypassing the normal event flow (i.e. the behavior occurs without dispatching the xforms-recalculate event).
As a result, instance data nodes whose values need to be recalculated are updated as specified in the processing model.
In general, the XForms processor automatically runs this action when required (e.g. at the end of an action sequence). As such, this action is included mostly for completeness.
However, the form author may need to force an earlier recalculation if there is a setvalue action whose XPath references depend on the recalculated results of prior setvalue actions.
