Dear World Wide Web Consortium,

The DTD for the HTML 4.01 Frameset DTD is slightly malformed, which
causes issues for XML compliant editors and XSL engines which import the
DTD.

In particular, the following section:

<!ENTITY % HTML.Version "-//W3C//DTD HTML 4.01 Frameset//EN"
  -- Typical usage:

    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN"
            "http://www.w3.org/TR/html4/frameset.dtd">
    <html>
    <head>
    ...
    </head>
    <frameset>
    ...
    </frameset>
    </html>
-->

Looks as if it should read:

<!ENTITY % HTML.Version "-//W3C//DTD HTML 4.01 Frameset//EN">
  <!-- Typical usage:

    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN"
            "http://www.w3.org/TR/html4/frameset.dtd">
    <html>
    <head>
    ...
    </head>
    <frameset>
    ...
    </frameset>
    </html>
-->

Best regards,

Aleatha Parker-Wood
