IE5 halts on well-formedness errors (as per the spec). And it's easy to build
parse trees from well-formed but invalid XML:

	<?xml version="1.0"?>
	<!DOCTYPE duckbill [
	<!ELEMENT platypus (bananas)>
	]>
	<doc>
	  <p>Hello world</p>
	</doc>

You can build a parse tree from "doc" and "p", even though the document is
invalid.

But any XML browser should at least have a validate button...
