XriSupported  includes XriUri, XriAuthentication, and  XriSecurity, which correspond to the IPP attributes of printer-uri-supported, uri-authentication-supported, and uri-security-supported.

Also, ServiceXriSupported comes from the IPP printer-xri-supported attribute (RFC 3380).

However, it may be argued that the, aside from configured Services and perhaps state, the Cloud Services do not  need any of the Local Service and System information sent; rather, this information is ultimately for the User.  The question then is whether the User  (in any role)  has a need for this information.  The question may be applied to all of the currently identified local system and service elements, the values of which are to be communicated to the Cloud  Services..

Probably don't need XriSupported or ConfiguredServices.

Probably don't need OperationsSupported, ServiceXriSupported, or VersionsSupported.
