Short and probably obvious problem: what can I do to be asked for more properties while creating DTML Document (say I wanna be asked about description and keywords which I use in meta tags)? Maybe, customize "OFS/methodAdd.dtml" and "OFS/documentAdd.dtml".

You need to change the "action", too, and do something with the new properties. The code for this handling is in "OFS/DTMLMethod.py" and "OFS/DTMLDocument.py", respectively. Dieter
