Feels a bit like XIST. Is the class def per element type mandatory? If not, what do defaults look like? For my part, I think that there are so many XML processing idioms based on user preference that I'd balk at blessing any one. In retrospect I think it was a mistake to even bless SAX and DOM by putting them in the stdlib. I think that XML processing is parallel to Web frameworks in this respect. I suppose an equivalent of BaseHTTPServer makes sense, but IMO minidom, SAX and pulldom already serve for that. Nevertheless, I've been looking forward to seeing this module of yours for a while and I'll try to test it out and provide some feedback. -- Uche Ogbuji Fourthought, Inc. http://uche.ogbuji.net http://fourthought.com http://copia.ogbuji.net http://4Suite.org Articles: http://uche.ogbuji.net/tech/publications/ _______________________________________________ XML-SIG maillist - XML-SIG@python.org http://mail.python.org/mailman/listinfo/xml-sig
