I suspect that you're right on most of those points, though I also
think its difficult to get good metrics on XML usage as it tends to
overlap both C and Java communities. It's also worth distinguishing
those cases where the programmers are consciously manipulating XML -
DOM coding, XSLT, using an XML presentation language, etc., from those
where the XML is either an unmanipulated serialization format or is
infrastructure (web services) that doesn't present an overt
angle-bracket face to the developer.
You can tell Java developers who understand XML from those that don't.
Those who don't often tend to have overspecified object model
hierarchies and like to boast of using hundreds of classes - the ones
who do typically have far simpler interfaces, prefer to put most of
the hierarchical complexities into the XML, and usually can be found
at the beach during the summer.
