There is Boost precedent for this e.g. boost::phoenix or 
boost::python.

In short, your namespace would be boost::mpl. MPL98 might be rehoused 
into boost::mpl::v1 and yours might be mapped into boost::mpl::v2. A 
C macro define then maps the user selected namespace version into 
boost::mpl, with the default usually being the most recent version.

For now you can use boost::mpl::v2 safely. If you just happened to 
invest the work in remapping existing MPL into boost::mpl::v1 in 
preparation but keeping v1 mapped into boost::mpl, I would doubt 
anyone here would complain.
