This function will perform the central debug of all the XMLDB classes being called automatically every time one error is found.
Apart from the main actions performed in it (XMLDB agnostic) it looks for one function called xmldb_debug() and invokes it, passing both the message code and the whole object. So, to perform custom debugging just add such function to your libs.
Call to the external hook function can be disabled by request by defining XMLDB_SKIP_DEBUG_HOOK
