"--valid" seems to be reserved for DTD validation.
A sketched modification of xmllint.c - if you just need a quick local
change:

1. New functionallity, new variable:
    static int wxsivalid = 0;
2. Process a new command line argument:
    } else if ((!strcmp(argv[i], "-wxsivalid")) ||
        (!strcmp(argv[i], "--wxsivalid"))) {
            wxsivalid++;
            noent++;
    }
3. Modify the schema validation handler to validate even
    if no schema was created:
    } else if ((wxschemas != NULL) || (wxsivalid)) {
