I mean that Doxygen needs to support parsing .qml files and .cpp files
containing QML files (and that it should generate the same look of content
for both of them).

Doxygen does not support everything we need. Maybe at some point we (the
Qt project) will not require any new features from the documentation tool,
then we can obviously just ship a Doxygen version that is known to work.
What I mean is that in the beginning we'll probably have a situation
similar to Gerrit, where we have a version deployed with the Qt project
that is mainline with some extra patches applied (which is a fork in my
book, or at least temporarily, until the patches are integrated in

That would not occur when Doxygen releases are lined up with Qt (or when
we get lucky and Doxygen releases a version before a Qt release which has
all our patches applied).
