OK - modelof would be nice but:

1 We could get \modelof added to Doxygen.

2 The key information DefaultConstructible is present - a big improvement on the current situation.
And if you go to the source hpp, you will also find the comment with this info.

I have a long term vision of starting with Clang and adding the documenting-from-comments features,
but we are way off that. A GSoC project?

We also perhaps don't want to put a lot of work into making BOOST_CONCEPTS work automatically, only
to find that it obsolete if concepts are added to C++.

For a year or several, we should be using the tools we have to best.

If you wish I could tackle this now - but I'm too busy with a bout of industrial strength DIY at
present ;-)

But when I'm free, is this worth tackling?

It's OK - but it's very much reference info - it doesn't have hyperlinks to explain much - not even
links to the source files!

As an test example, it's also a bit of a googly because Fusion a bit of a weird and wonderful
meta-language-ish beast.

Another test-case example?
