> 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 ).
