Re: [Geopriv] PLEASE TAKE NOTE: Fwd: [Technical Errata Reported] RFC4480 (3121)

Since the extension point in the existing schema is marked ##other and lax,
a processor with an old schema will reject an instance document that
contains the "unknown" {urn:ietf:params:xml:ns:pidf:rpid}:lunch element.

That's a backwards compatibility break.

> Erratum #2959 claimed that the element "lunch" needs to be removed from the specification since it is not included in the schema. However, the schema was in error. This erratum corrects the schema so that, if approved, IANA can update the information at http://www.iana.org/assignments/xml-registry/schema/pidf/status/rpid.xsd
