typedef void(XMLCDECL *) typede void) (XMLCDECL *xmlValidityWarningFunc)(void *ctx

xmlValidityWarningFunc: @ctx: usually an xmlValidCtxtPtr to a validity error context, but comes from ctxt->userData (which normally contains such a pointer); ctxt->userData can be changed by the user. @msg: the string to format *printf like vararg ...: remaining arguments to the format

Callback called when a validity warning is found. This is a message oriented function similar to an *printf function.
