I'm having problems parsing this with all of the python xml parsers:

<?xml version="1.0"?>
<!DOCTYPE top  [
	<!ENTITY linklist SYSTEM "links.xml">
	<!ENTITY classification SYSTEM "classification.xml">
]
>
<top>
	&linklist;
</top>

Is my brain mush? Whats wrong with this? I get no errors, but I also get
no DOM tree. Is this a problem with the XML here, the parser, or the DOM 
builder? If I try to parse a more "vanilla" XML file, I get a DOM tree
just fine:

<top>
<head>
This is head text
</head>
<body>
This is body text
</body>
</top>

It does have the same problem (upcasing). XML is case sensitive, while 
SGML is not -- SX assumes it the incoming data is SGML and therefore
ignores the case of the incoming element tags text. Is there an option for
SX to behave case sensitively? (as an aside, I wish they had named it
something besides SX, since the xmodem protocol handler also has a binary
named sx)
