If the part does not have a polarity or pin 1 marking, what difference does
it make ?
There will probably be more mistakes if people down the line have to map
pin1 to pin28,
use the K.I.S.S. principle.

  I whole heartly agree !!!

but its sad to say I've run into more young engineers who make there own
standards.
I had one who could not understand why it wasn't good pratice to use a
signal name
instead of a pin number.
or better yet why he couldn't make up his own ref des's using part numbers.
