Hi GnuPG folks--

I just noticed that a couple places in doc/DETAILS and doc/gpg.texi
refer to "conventional encryption".  Does this mean "symmetric
encryption" or something else?

More concretely, i'm assuming it refers to "SKESK[0]-prefixed SEIPD[1]
packets".  Is this correct?

In 2015, i'm not sure whether this is any more "conventional" than
PKESK-prefixed SEIPD packets.  Should the term be explained somewhere?
