Hi Eric, Great job on the latest PEP 421. I really like it. A few additional comments/questions. * sys.implementation.version This is defined as the version of the implementation, while sys.version_info is the version of the language. The semantics of sys.version_info have been suff

Re: [Python-Dev] c/ElementTree XML serialisation

Furthermore, if I use the "html" method (an option given to ElementTree.write), closing tags are converted to lower case, which leads to an XML parsing error with camel-cased tag names. Using the "text" method instead removes all tags, and I get a ValueError if I try to use the "c14n" method. T

This really isn't the right mailing list to ask this kind of question (I know you got help last time with your Debian-specific problem, but that was because people got overly excited =). Python-dev is meant for discussing the development *of* Python, not using it or developing *with* it. I would t
