import module namespace icdml = "http://www.zorba-xquery.com/modules/store/static/integrity_constraints/dml";
This module defines a function to check if an integrity constraint is satisfied. The integrity constraint needs to be declared in the prolog of a module.
This module is part of Zorba's XQuery Data Definition Facility. All the integrity constraints managed by this module have to be pre-declared in the prolog of a module. Please refer to the general documentation for more information and examples.
