</xs:complexContent> </xs:complexType> </xs:schema> Notes ----- The complex types "controlType", "ackType", "capabilitiesType" and "requestType" define extension points by using xs:any with namespace ##any. This violates the "Unique Particle Attribution" rule for XSD 1.0 (see: https://www.w3.org/wiki/UniqueParticleAttribution) and shows up as an error in some tools. I suggest changing the namespace to ##other like it's done in other schemas (for example, RFC7865 defines extension points in this way: https://datatracker.ietf.org/doc/html/rfc7865#section-9 ). [Verifier note:] Replace all four occurrences of: <xs:any namespace="##any" processContents="lax"> with: <xs:any namespace="##other" processContents="lax"> -------------------------------------- RFC8147 (draft-ietf-ecrit-ecall-27) -------------------------------------- Title : Next-Generation Pan-European eCall Publication Date : May 2017 Author(s) : R.
