The "dots" may have been nothing more than mounting points for self adhesive tell-tales which are famous for loosing their ribbons. They will be on opposing sides of the sail along the luff and likely a few near the mid-points of the sail.
Removing the hanks and adding a luff-tape is not a costly process, nor is adding a strip of dark Sunbrella along the foot and the leach for sun protection. I don't know if the CDI can be used for reefing but if so, and you intend to use it that way, have your sail maker add some rope sewn into pockets along the luff near the mid-point so that the sail will maintain at least some of its shape while reefed (remembering of course, to adjust your sheet leads as well).
"It is not so much for its beauty that the sea makes a claim upon men's hearts, as for that subtle something, that quality of air, that emanation from the waves, that so wonderfully renews a weary spirit."
