[Zope] Zope Book: WYSIWYG Tools for Page Templates?

Hi! The ZPT chapter of the Zope Book <http://zope.org/Documentation/Books/ZopeBook/2_6Edition/ZPT.stx> names Netscape Composer and Amaya as WYSIWYG tools for Page Templates. Does anybody use them? Does it work? AFAICT at least the current Mozilla Composer 1.7 / Nvu 0.20 and Amaya 8.5 in WYSIWYG mode remove TAL and METAL attributes. I'm currently working on the 2.7 edition of that chapter. If nobody can give me a hint how to use Composer or Amaya, I'll remove their names. OpenOffice 1.1 also deletes unknown attributes. Are there any other open source WYSIWYG tools that can be used for Page Templates? Or just Dreamweaver and GoLive? Cheers, Yuppie
