Form required attribute validation error

I'm trying to put the final touches on a site that I'm building and I'm coming up with a validation error that I can't figure out. It involves the use of the "required" attribute in one of my forms. Here is the form code:

<div id="sub">
    <form id="subForm" action="MAILTO:[email protected]" method="post" enctype="text/plain">
        <label class="floatLabel" for="subBox"><b>ENTER YOUR EMAIL IN THE BOX BELOW TO SUBSCRIBE TO OUR NEWSLETTER</b></label> <br/>
        <input type="text" name="subBox" id="subBox" size="20" required /> <br/>
    <fieldset id="buttons">
        <input type="submit" value="Subscribe" />
        <input type="reset" value="Cancel" />
    </fieldset>
    </form>
</div>

I'm using a transitional doctype.

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
  "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

Checking with W3C Markup Validator; this is the error that keeps coming up:

Line 116, Column 69: "required" is not a member of a group specified for any attribute

        <input type="text" name="subBox" id="subBox" size="20" required /> <br/>

This is the only error that I'm getting, but as near as I can tell, I'm using the required attribute correctly. It renders correctly in the browser and works as expected.

Any thoughts as to why I'm getting this validation error?? Thanks.

Write only < !DOCTYPE html > and than it will work

The required attribute is an HTML5 attribute and not allowed according to older HTML specifications, such XHTML 1.0.

Consider using HTML5 validation instead, using the doctype string

<!DOCTYPE html>

Beware that HTML5 does not allow all XHTML 1.0 features, especially if you are using XHTML 1.0 Transitional.
