What does the deed of movable hypothec have to specify in the case of a universality of movable property?

In Quebec, if it is about a universality of movable property, the deed of movable hypothec must indicate the nature of this entire category of property.

The movable hypothec which is a charge over a universality of property carries itself over the property of the same nature which replaces the one that was alienated in the course of the activities of the business.

The movable hypothec which is a charge over a universality of property subsists, in spite of the loss of the hypothecated property, when the debtor or the constituent replaces it within a reasonable time limit.
