Standard says (4.41  SQL-transactions):

         It is implementation-defined whether or not the non-dynamic or
         dynamic execution of an SQL-data statement or the execution of
                                 ^^^^^^^^^^^^^^^^^^
         an <SQL dynamic data statement> is permitted to occur within the
                                         ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
         same SQL-transaction as the non-dynamic or dynamic execution of
         ^^^^^^^^^^^^^^^^^^^^^^^
         an SQL-schema statement. If it does occur, then the effect on any
         ^^^^^^^^^^^^^^^^^^^^^^^

So, you see that this idea came not to Oracle only...

I don't object against DDLs inside BEGIN/END.
I just mean that it's not required by standard.
If someone is ready to fix this area - welcome.
