Need help to get started with Mallard

[Leonardo Ferreira Fontenelle <leonardof gnome org>]

I wrote an index page, mostly the same as the one in the Ten Minutes Tour, and I can't have it converted to a (x)html page. What else should I do?

$ cat index.page
<page xmlns="http://projectmallard.org/1.0/" type="guide" id="index">
<title>Referência Médica</title>
</page>
$ gnome-doc-tool xhtml index.page
Unmatched element: page
Unmatched element: title

For me it seems that the syntax is correct. Isn't gnome-doc-utils (0.18) recognizing it as a Mallard page? Do I need to set up autottool files and the GNOME help  directories hierarchy? I'd like to try Mallard outside software documentation...

Thanks in advance!
