What is Pashmina?

Wikipedia http://en.wikipedia.org/wiki/Pashmina states the following regarding pashmina:

Some manufacturers use the term pashmina to describe an ultra fine cashmere fiber; others use the term to describe a blend of cashmere and silk. The Federal Trade Commission (FTC) encourages manufacturers and sellers of products described as pashmina to explain to consumers, on a hangtag, for example, what they mean by the term. As with all other wool products, the fiber content of a shawl, scarf or other item marketed as pashmina must be accurately disclosed. For example, a blend of cashmere and silk might be labeled 50% Cashmere, 50% silk or 70% Cashmere, 30% Silk, depending upon the actual cashmere and silk content. If the item contains only cashmere, it should be labeled 100% Cashmere or All Cashmere. The label cannot say 100% Pashmina, as pashmina is not a fiber recognized by the Wool Act or regulations.
