Definitions explain things by relating them to other things.

"Reserved" here means, if you use "xmlfoo", and a later version defines
"xmlfoo" in a way that conflicts with your use, and your stuff breaks
because of that, then that is entirely your fault. You cannot jump from
"reserved" to "must not" to "not valid" and then to "not well-formed".
The last three terms all have well-defined semantics in the context of
the XML specification, and the definition of "well-formed" does not in-
clude any provisions about the use of reserved names.
