What does "well-formed" mean?
The concept of a well-formed document is something that is really new in XML. A document that is well-formed is easy for a computer program to read, and ready for network delivery.
Specifically, in a well-formed document:
    -    All the begin-tags and end-tags match up 
    -    Empty tags use the special XML syntax (e.g. <empty/>) 
    -    All the attribute values are nicely quoted (e.g. <a href="http://www.test.com/xml.html">) 
    -    All the entities are declared (entities are re-usable chunks of data, much like macros, part of XML's inheritance from SGML).
