Sure the idea is that you give the validate attribute a unique name to group the fields you do want validated together like below:
<div><inputtype="text"validate="form1"require="Please enter name"/><inputtype="submit"value="Submit"onclick="return validate('form1');"/></div><div><inputtype="text"validate="form2"require="Please enter name"/><inputtype="submit"value="Submit"onclick="return validate('form2');"/></div>
Thanks for the feedback, I'll look at updating the example in the download to make this more clear.
