Re: [docbook-apps] Website. docbook v5? Schema issues

website 1.26
website.dtd contains

<!-- *********************************************************************

Anyone know what customization is talked of here?
Another comment reads

<!-- allow some things that would be excluded by simple -->

Implying this is derived from, and extends, a 'simple'
docbook dtd?

I don't know of any customization tool working on DTD's?

Anyone help please?
