title: Use error in form without a field binding?
body: <p>I am wondering whether you can use a &lt;form:errors&gt; tag to display an error that doesn't have a binding to a field in the command object. Basically I want to do some custom validation logic that isn't directly related to a single form element, but perhaps many or all, or none. What if I only wanted to validate forms from 9am to 3pm?</p>
  
  <p>I tried creating a global error like Errors.reject("myError"), but then how do I put this in the jsp? Must I make an attribute just for this in the command object?</p>
