Requestor of revision?

["Jean Jordaan" <jean.jordaan@gmail.com>]

Hi there

I have a specification document with a revision history (changes to the
specification), but each revision states who requested the change. I
want to markup it as follows::

    <revision>
        ...
        <author>
            <corpauthor>...</corpauthor>
            <contrib>Requestor</contrib>
        </author>
    </revision>

Does anyone know of a better way?
