visual studio debugger visualizer maximum template support

Question

I am using visual studio 2010 and wanted to update my debugger visualizer to show correctly my boost::variant instance. I found this page: https://svn.boost.org/trac/boost/wiki/DebuggerVisualizers and here https://svn.boost.org/svn/boost/sandbox/boost_docs/subprojects/DebuggerVisualizers/variant.vis.txt an implementation to boost variant that support up to 9 template argument. sadly we have 12 argument and the last 3 have no visualizer representation. I tried to add support for the last 3 argument but nothing has changed:

boost::variant<boost::detail::variant::recursive_flag<*>,*,*,*,*,*,*,*,*,*,*,*,*>|boost::variant<*,*,*,*,*,*,*,*,*,*,*,*,*> {

What am I doing wrong? Thanks
