I didn't speak clearly. The issue isn't really SGML vs XML here, it's
DTD validation.

You can't make this work:

    <para xmlns:xlink="...">
      <emphasis xlink:href="...">...</emphasis>
    <para xmlns:xl="...">
      <emphasis xl:href="...">...</emphasis>

You can make either prefix (xl: or xlink:) work in any given document,
but as soon as you mix them, DTD validation is out the window.

                                        Be seeing you,
