[[student,PhD],[get,[price,reduced|for [conference,ETAP]]]]
Notice the transformation from passive to active voice in the second example. Nested frames can be unnested using a component included with the grammar, the unnester, which for the last example yields
[N:student,N:PhD][N:student,V:gets] [V:gets,N:price] [P:it,V:reduced] [V:reduced,N:price][N:price, for N:conference][N:conference,N:ETAP]
