//	Lists the paths to the specified product. A path describes how the user gets
//
// access to a specified product and is necessary when provisioning a product. A
// path also determines the constraints that are put on a product. A path is
// dependent on a specific product, porfolio, and principal.
//
// When provisioning a product that's been added to a portfolio, you must grant
// your user, group, or role access to the portfolio. For more information, see [Granting users access]in
