Hello, (I'm still looking for some good docs about zope way of thinking. The zope book is great btw) Let's imagine I'd like to add a keywords property to every dtml documents I have in my site. Do I need to add some "keywords" property to each dtml document I have? Shouldn't it be better to first create a zclass based on a dtml doc with this property already defined (with default values for example), and use this in place of the standard dtml docs. This may be problem as the site would not be standard. I'd like to still have standard dtml docs with added properties. Can I create a special management screen in order to let managers create new docs and edit existing ones? Is it needed? Or am I missing something with dtml-doc? It is quite important, because I want to make the work well at the beginning, else it will be a pain to change every doc because I didn't plan enough. Sorry for the simple question, if anyone could answer and point me to the right docs... Thanks ! Philippe Jadin
