Can an ORACLE_SID contain an underscore?

All the documentation I can find says it can, but I have seen posts on the internet saying you can't. Also a colleague had a problem where he called a database XX_611 which would not work because Oracle thought it was RAC instance 611, and you can only have 255 (Or similar) rac instances. I also note that many Oracle supplied tools don't like having an underscore in the ORACLE_SID, notably the dbca where as the manual db creation accepts underscore.
Documentation I looked at includes:
http://docs.oracle.com/cd/E11882_01/install.112/e24321/rev_precon_db.htm#i1027493
Support doc ID: 239888.1

Howdy, Stranger!
