   This document defines an ALTO extension that allows a resource to
   provide not only preferences of network paths but also correlations
   of network paths, including aggregations of network components and
   their properties on the paths between different PIDs or endpoints.
   The extended information can be used to improve the robustness and
   performance for applications in some new usage scenarios, such as
   high-speed data transfers and traffic optimization using in-network
   storage and computation.  This document introduces abstract network
   element (ANE) as an abstraction for aggregations of network
   components.  It extends the base protocol and the Unified Property
   extension to enable the capability of encoding such information in a
   "path vector", i.e., an array of ANEs that are traversed by traffic
   from a source to a destination.
