Not really corecmd_executable_file just identifies the label as being an
executable, which lots of apps will be allowed to execute without a
transition.
domain_type identifies the label as something that applies to a process,
domain_entry_file says that you can start a process labeled myapp_t, by
executing an executable labeled myapp_exec_t. BUT you still need to
write a transition rule, like domtrans_pattern(unconfined_t,
myapp_exec_t, myapp_t)
Which would say when a process labeled unconfined_t executes an
executable labeled myapp_exec_t, it will transition to a process labeled
myapp_t.
