Summary: Incomplete list of escape sequences

Initial Comment:
There exist some special character tags (i.e. 
beginning with &) that cause exceptions in minidom - 
and probably in other modeules, too. Example below:

=== PYTHON CODE ===
import xml.dom.minidom 

def do(text):
	print "Processing: ", text
	dom = xml.dom.minidom.parseString(text)
	print "... ok"

do("<body> this is ok </body>") #ok
do("<body> &lt; &gt; &amp; &quot; </body>") #ok
do("<body> &pound;  </body>") # error

=== STDOUT ===
Processing:  <body> this is ok </body>
... ok
Processing:  <body> &lt; &gt; &amp; &quot; </body>
... ok
Processing:  <body> &pound;  </body>

=== STDERR ===
Traceback (most recent call last):
  File "err.py", line 10, in ?
    do("<body> &pound;  </body>") # exception
  File "err.py", line 5, in do
    dom = xml.dom.minidom.parseString(text)
  File "C:\PYTHON22\lib\xml\dom\minidom.py", line 965, 
in parseString
    return _doparse(pulldom.parseString, args, kwargs)
  File "C:\PYTHON22\lib\xml\dom\minidom.py", line 952, 
in _doparse
    toktype, rootNode = events.getEvent()
  File "C:\PYTHON22\lib\xml\dom\pulldom.py", line 255, 
in getEvent
    self.parser.feed(buf)
  File "C:\PYTHON22\lib\xml\sax\expatreader.py", line 
111, in feed
    self._err_handler.fatalError(exc)
  File "C:\PYTHON22\lib\xml\sax\handler.py", line 38, 
in fatalError
    raise exception
xml.sax._exceptions.SAXParseException: <unknown>:1:7: 
undefined entity

=== COMMENTS ===
It is also my observation that special character tags 
(aka HTML escape 
sequences) translations are scattered "hither and 
thither" throughout 
modules
in the XML subdirectory, and that it would be better 
if they were all
put in one place.

I might be persuaded to help with the maintenance work 
that this 
would require!
