Form validation & default values

[eluser]antiver[/eluser]
Well yeah, but

Code:

<input type="text" name="email" value="<?=$this->validation->email?>">

is already inserting a value, so I assumed the validation class should have a function to set an initial, default value. If not, how do I insert both (the initial, default value and the validation results)? I'm sure I could hack it together and make it work, but isn't there a standardized (or provided) way to do this?
