REPOST: Where is select for update nowait skip locked documented?

Hello out there,

some time ago I read here in this newsgroup that the following SQL is valid:

select * from my_table for update nowait skip locked;

I checked it out and it works. But it seems to be missing in the documentation.
I Looked the SQL reference of 8.1.7 and 9i but it's not there. Then I had a look at the index of the documentation searching for "skip" but again no success.
Now the questuion is: Is the SQL intentionally undocumented or is that simply a mistake? Or am I too blind to find it in the docs?

Regards,
Lothar
