On two occasions, the xml package uses environment variables to override parser / DOM implementations: xml.sax package and xml.dom.domreg module. On both occasions, the code should not use env vars to override module names, when the interpreter is started with flags like -E or -I.

Christian: do you think that this issue is severe enough to justify to backport it to Python 3.4 and 3.5? I don't think so. Python 2.7, 3.6, 3.7 and master (future 3.8) already have been fixed, IMHO it's enough and this issue can be closed.
