RFC 7852, "Additional Data Related to an Emergency Call", July 2016

Errata ID: 8519
Status: Reported
Type: Technical
Publication Format(s) : TEXT
Reported By: Robert Stepanek
Date Reported: 2025-07-23

Section Appendix A says:

     <!--
       6.1.3
     -->
     <xs:element name="source">
       <xs:complexType>
         <xs:sequence>
           <xs:element name="parameters">

It should say:

     <!--
       6.1.3
     -->
     <xs:element name="source">
       <xs:complexType>
         <xs:sequence>
           <xs:element name="parameters" minOccurs="0">

Notes:

The XML schema in Appendix A is based on the Relax NG schema defined in RFC 6351. There already is a verified errata 2994 for RFC 6351 which updates the Relax NG schema to define the parameters of the SOURCE property to be optional. The XML schema in RFC 7852 should be updated accordingly.

Note that RFC 7852, Section 11.6. registers the XML schema in the IANA XML Registry, so the XML schema at IANA should be updated as well.

The contents of this errata were originally highlighted by John Scott on the vcarddav and the ecrit mailing lists. See https://mailarchive.ietf.org/arch/msg/ecrit/JPCturATh0WN1rQfyF4M6EAkar0/
