Many bug fixes, have tested locally. I don't think that this is on the critical path.

• Fri Oct 30 2009 Jeffrey C. Ollie jeff@ocjtech.us - 2.2.3-1
• 2.2.3 (2009-10-30)
• Bugs fixed
• • The resolve_entities option did not work in the incremental feed
• parser.
• • Looking up and deleting attributes without a namespace could hit a
• namespaced attribute of the same name instead.
• • Late errors during calls to SubElement() (e.g. attribute related
• ones) could leave a partially initialised element in the tree.
• • Modifying trees that contain parsed entity references could result
• in an infinite loop.
• • ObjectifiedElement.setattr created an empty-string child element
• when the attribute value was rejected as a non-unicode/non-ascii
• string
• • Syntax errors in lxml.cssselect could result in misleading error
• messages.
• • Invalid syntax in CSS expressions could lead to an infinite loop in
• the parser of lxml.cssselect.
• • CSS special character escapes were not properly handled in
• lxml.cssselect.
• • CSS Unicode escapes were not properly decoded in lxml.cssselect.
• • Select options in HTML forms that had no explicit value attribute
• were not handled correctly. The HTML standard dictates that their
• value is defined by their text content. This is now supported by
• lxml.html.
• • XPath raised a TypeError when finding CDATA sections. This is now
• fully supported.
• • Calling help(lxml.objectify) didn't work at the prompt.
• • The ElementMaker in lxml.objectify no longer defines the default
• namespaces when annotation is disabled.
• • Feed parser failed to honour the 'recover' option on parse errors.
• • Diverting the error logging to Python's logging system was broken.
