[jQuery] JQuery YAV plugin inputclasserror question

[MACE]

For the YAV plugin, can you use the option 'inputclasserror' by
itself?

$("#form1").yav({
    inputclasserror : "fieldError"
});

Do you need the 'errorMessage' option work this to work?

$("#form1").yav({
     errorMessage : "Errors are found"
},{
     inputclasserror : "fieldError"
});
