-// Package extensions provides information and interaction with the different
-// extensions available for the OpenStack Neutron service.
-//
-// The purpose of Networking API v2.0 extensions is to:
-//
-// - Introduce new features in the API without requiring a version change.
-// - Introduce vendor-specific niche functionality.
-// - Act as a proving ground for experimental functionalities that might be
-//   included in a future version of the API.
-//
-// Extensions usually have tags that prevent conflicts with other extensions
-// that define attributes or resources with the same names, and with core
-// resources and attributes. Because an extension might not be supported by all
-// plug-ins, its availability varies with deployments and the specific plug-in.
