Yes, that's the DC convention adopted to AC. Just be sure to put a
dot on the input side so everyone will know it's the input reference. :-)
That convention also applies to baluns and transformers.

The dot indicates phase polarity.

I must admit I don't like the sound of that one bit. Sounds like you're
describing the direction a "wave" is "traveling", when we know that the
"wave" is really just "standing" there. :-)

I didn't invent the 'AC current flowing away from the source' convention
but most of the tools and concepts that I was taught assume such.

Maybe they taught this "convention" in grade school back in the
'40's? I don't know what application it might have here. Maybe you
could point to somewhere in 95-1 where they make use of this
"convention". Or indicate how it might apply to a coil having
alternating current going "in" from both ends.
