During the development of Python 2.5, an attempt to move the "xml" 700 # package implementation to a new package ("xmlcore") proved painful. 701 # The goal of this change was to allow applications to be able to 702 # obtain and rely on behavior in the standard library implementation 703 # of the XML support without needing to be concerned about the 704 # availability of the PyXML implementation. 705 # 706 # While the existing import hackery in Lib/xml/__init__.py can cause 707 # PyXML's _xmlpus package to supplant the "xml" package, that only 708 # works because either implementation uses the "xml" package name for 709 # imports. 710 # 711 # The move resulted in a number of problems related to the fact that 712 # the import machinery's "package context" is based on the name that's 713 # being imported rather than the __name__ of the actual package 714 # containment; it wasn't possible for the "xml" package to be replaced 715 # by a simple module that indirected imports to the "xmlcore" package. 716 # 717 # The following two tests exercised bugs that were introduced in that 718 # attempt.
