RFC 6505
A Mixer Control Package for the Media Control Channel Framework
5. Formal Syntax
This section defines the XML schema for the Mixer Control Package. The schema is normative. The schema defines datatypes, attributes, and mixer elements in the urn:ietf:params:xml:ns:msc-mixer namespace. In most elements, the order of child elements is significant. The schema is extensible: elements allow attributes and child elements from other namespaces.
Elements from outside this package's namespace can occur after elements defined in this package. The schema is dependent upon the schema (framework.xsd) defined in Appendix A.1 of the Control Framework [RFC6230]. <?xml version="1.0" encoding="UTF-8"?> <xsd:schema targetNamespace="urn:ietf:params:xml:ns:msc-mixer" xmlns:fw="urn:ietf:params:xml:ns:control:framework-attributes" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="urn:ietf:params:xml:ns:msc-mixer" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <xsd:annotation> <xsd:documentation> IETF MediaCtrl Mixer 1.0 (20110104) This is the schema of the Mixer Control Package.
