Subject: DOCBOOK-APPS: Re: SGML vs XML
/ Yann Dirson <ydirson@users.sourceforge.net> was heard to say: |> The proposed linking extensions will add XLink-namespaced attributes |> more-or-less throughout. That works fine in SGML, until someone uses a |> different xmlns declaration for the XLink namespace in different parts |> of the same document. | | Why should it be a problem ? That's something an XML author could | want to do, but that would just not be available to SGML authors. Or | do I miss the point ? I didn't speak clearly. The issue isn't really SGML vs XML here, it's DTD validation. You can't make this work: <section>... <para xmlns:xlink="..."> <emphasis xlink:href="...">...</emphasis> </para> <para xmlns:xl="..."> <emphasis xl:href="...">...</emphasis> </para> </section> 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.
