Interface XMLAssertHandler

All Superinterfaces:

XSAssertionXPath2Value

All Known Implementing Classes:

XMLAssertAdapter, XMLAssertPsychopathXPath2Impl

public interface XMLAssertHandler
extends XSAssertionXPath2Value

The implementation of this interface will invoke an external XPath engine, that would evaluate the XPath 2.0 expressions for XML Schema 1.1 assertions. This interface communicates with the XMLSchemaValidator and accepts context information required by the external XPath engine. If assertions evaluation would return 'true', validation would proceed further checking the remaining validation constraints.
