I was having trouble with this.  I was getting error about
BOOST_SPIRIT_DEBUG_NODE not being defined:

x3-employee-beg_end_attr_actions.cpp:94:9: error: unknown type name 
'BOOST_SPIRIT_DEBUG_NODE'
         BOOST_SPIRIT_DEBUG_NODE(employee);
         ^
1 error generated.

So, grep'ed for that macro and found:

So it appears that only works for classic or karma but not for x3?
