I'm sure you can find the answer to your question in the GNAT documentation
(RTFM), but keep in mind:

From the Ada 95 Reference Manual A.2:
(2) In the standard mode, it is illegal to compile a child package of Ada.

Also note: From A
(4) The implementation may restrict children of language-defined library
units (other than Standard).


In my opinion it is not a good practice to create packages that are children
of Ada.
