David is right. The former VRML group, now X3D, is having
a heckuva row over the XML-encoding in X3D. A group of the
VRMLers with content and/or implemented engines fight the
XML encoding tooth and nail. The majority of the new members
come in with some XML background and a solid conviction that
XML opens up 3D to more users and applications. These don't
tend to be the C++ programmers who are more likely to support
the curly bracket camp. On the other other hand, all of the
new interchange syntaxes such as Collada are XML-based and
the arguments there are NIH and the use of elements vs
attributes (sorta myopic but there it is).
It is an interesting debate from a social perspective.

It might depend on the audience. A few years ago, I did a major
restructuring of the Open Source FlightGear simulator, moving as much
of the configuration as possible out of the C++ and into XML (the
physics models for aircraft were already using a pseudo-XML, but
everything else was hard-coded). A short while after that, the
contributor base grew enormously, drawing in people with little or no
programming experience but other useful skills, such as 3D modelling,
aerodynamics, etc.
So, in this case, the majority of *coders* know C++ better than XML,
but the majority of *contributors* know only XML. They don't know it
all that well, but XML doesn't have to be hard -- just make sure the
tags match, escape the special characters, quote the attributes, and
remember that names are case sensitive.
