Html5 validate input value not eqaul to by default value

I want to validate input value not equal to by default value through html5 validation,is it possible?

 <input type="text" name="First Name" value="First Name" id="FirstName"
 required=""  title="First Name is Required!" >

when user click on submit button, if input filed has value= First Name then show error.

I don't want to use placeholder="First Name".

Is there a way to validate using pattern attribute, like pattern="!First Name" <-Stupid logic :)
