I found some doc about it, but I confused. Oracle has two similar kind of 
objects: packages and modules. Ansi SQL defines MODULES. 

http://64.233.183.104/search?q=cache:jkXyiDKg-sgJ:www.oracle.com/technology/products/rdb/pdf/createmodule_external_routines.pdf+%22CREATE+MODULE%22+sql&hl=cs&ct=clnk&cd=4

Has anybody more documentation about it?
