This was an internal function which has been removed since 2.7. Any
reference to it in the manual should be removed.

If you are thinking of externalise an Any, my advice is to marshal the An=
y
value into a MemBufferedStream and extract the content as a sequence of
Octet. There is no portable way to do so I'm afraid. If you need code
example, please search the archive.
