    Just in case it isn't clear (like I had), an example:

    <?php

    $domDocument     = new DOMDocument('1.0', "UTF-8");
    $domElement = $domDocument->createElement('field','some random data');
    $domAttribute = $domDocument->createAttribute('name');

    // Value for the created attribute
    $domAttribute->value = 'attributevalue';

    // Don't forget to append it to the element
    $domElement->appendChild($domAttribute);

    // Append it to the document itself
    $domDocument->appendChild($domElement);

    ?>

    Will output:
    <?xml version="1.0" encoding="UTF-8"?>
    <field name="attributevalue">some random data</field>
