title: mvc3 validate input 'not-equal-to'
body: <p>My forms have inputs with default helper text that guides the user on what to enter (rather than using labels). This makes validation tricky because the input value is never null. </p>
  
  <p>How can I extend unobtrusive validation to handle this? The form shouldn't be valid if the Name input is equal to "Please enter your name..."</p>
  
  <p>I started reading <a href="http://bradwilson.typepad.com/blog/2010/10/mvc3-unobtrusive-validation.html" rel="noreferrer">Brad Wilson's blog post</a> on validation adapters, but I'm not sure if this is the right way to go? I need to be able to validate against different default values depending on the field. </p>
  
  <p>Thanks</p>
