This conversation is really becoming surreal. People, please, it's very simple: supporting the range of character references defined in XML 1.1. Is not, repeat *NOT* the same thing as being an XML 1.1 parser. If I have software that parses "<a>b</a>" that does not mean I have an XML 1.0 parser. If that software also accepts "<a>b</c>", then it is obviously not such. Any software that accepts "<body>this is a backspace: </body>" is neither a compliant XML 1.0 parser nor a compliant XML 1.1. parser. All XML 1.1 documents *must have an XML declaration* according to the strict stipulation of the spec. If an XML 1.1. parser encounters a document without an XML declaration, it *must* assume that it is an XML 1.0 document, at which point it would *have to* stop with a fatal error when it encounters . Period. There is no negotiation here. Therefore, as far as I can tell, neither the ET/sgmlop trick nor XIST are XML 1.1. parsers. I cannot speak for LTXML or pxdom, but knowing the authors, I would guess that they are indeed compliant XML 1.1 parsers. -- Uche Ogbuji Fourthought, Inc. http://uche.ogbuji.net http://fourthought.com http://copia.ogbuji.net http://4Suite.org Use CSS to display XML, part 2 - http://www-128.ibm.com/developerworks/edu/x-dw-x-xmlcss2-i.html XML Output with 4Suite & Amara - http://www.xml.com/pub/a/2005/04/20/py-xml.html Use XSLT to prepare XML for import into OpenOffice Calc - http://www.ibm.com/developerworks/xml/library/x-oocalc/ Schema standardization for top-down semantic transparency - http://www-128.ibm.com/developerworks/xml/library/x-think31.html _______________________________________________ XML-SIG maillist - XML-SIG@python.org http://mail.python.org/mailman/listinfo/xml-sig
