Indicate whether a process requires outgoing IPv4/IPv6 network
access. Choice of IPv4 or IPv6 is implementation and site
specific, correct tools must support both.

If `networkAccess` is false or not specified, tools must not
assume network access, except for localhost (the loopback device).

If `networkAccess` is true, the tool must be able to make outgoing
connections to network resources. Resources may be on a private
subnet or the public Internet. However, implementations and sites
may apply their own security policies to restrict what is
accessible by the tool.

Enabling network access does not imply a publicly routable IP
address or the ability to accept inbound connections.
