  <expression>if x > 0</expression>

"well-formed", not valid/invalid.  In XML, the distinction is 

<atag>></atag> is also well-formed, so if libxml2 won't accept it, 
someone should open a defect report.

On the other hand, this:

<atag>]]></atag> is *not* well-formed (but, umm, good luck writing a 
regex that makes it ill-formed, while allowing <![CDATA[<atag>example 
of ill-formedness</btag>]]>, which is perfectly well-formed.

Argue that they're corner cases, perhaps.

I don't know that I ever wanted greatness, on its own.  It seems rather
like wanting to be an engineer, rather than wanting to design something,
or wanting to be a writer, rather than wanting to write.  It should be a
by-product, not a thing in itself.  Otherwise, it's just an ego trip.
