[Homestead Maple]

On the card that IMSI is distributing to maple makers, it has the "Definition of Pure Maple Syrup" and the first paragraph reads;
Produced exclusively by the concentration of maple sap or by the solution or dilution of a maple product other than maple sap in potable water.
I wonder what it means 'by the solution or dilution of a maple product other than maple sap in potable water'?
Taking maple sugar and dissolving it with tap water to bring it back to maple syrup?
Also, the density that would be allowed reads;
Minimum soluble solids of 66% (66.5 - 67.5% for best flavour).
This would be a lighter density than some states allow now. I suppose maple makers would benefit from higher syrup yields, from their sap.
