Is there anyway to disable the client-side validation for dojo date text box? | In my example below I'm using a `dijit.form.DateTextBox`:



```
<input type="text" name="startDate" dojoType="dijit.form.DateTextBox" constraints="{datePattern:'MM/dd/yyyy'}"  value='<c:out value="${sessionScope.adminMessageForm.startDate}"/>' />

```

So for example, if the user starts to enter "asdf" into the date the field turns yellow and a popup error message appears saying `The value entered is not valid.`. Even if I remove the `constraints="{datePattern:'MM/dd/yyyy'}"` it still validates. 


Without going into details as to why, I would like to be able keep the dojoType and still prevent validation in particular circumstances.
