Is this a 'published hold'?
It depends. I'm going to go back a little on my earlier off-the-cuff answer.Let's say you are approaching from the west, and are given 'expect to hold at stv', would you expect this one, or the (vastly different) one on the iap?
Yes, but not a mandatory hold.
In the case of this, the chart lets you know that this is a holding point, but only depicts a general direction for the procedure. ATC would give you the specifics (direction, leg length/times, etc.) if the hold is assigned.
