Hi,

you're just a little too fast as I added the example in the 1.47 release. In 
the meantime, the submachine example can be found there:
http://svn.boost.org/svn/boost/trunk/libs/msm/doc/HTML/examples/CompositeTutorialWithEumlTable.cpp

It's slightly trickier than the main machine though. You need to define the 
front-end the "old" way, then inherit from the back-end and euml_state.

HTH,

Christophe
