1. In the specification and xsd file，can not find that how to describe the locator information of the domain participant such as metatrafficUnicastLocator or defaultUnicastLocator.
2. When the topicKind of a topic is WITH_KEY, how to describe the corresponding key-value information of the DateWriter in the "data_writer" part.
3. If user can add some bolcks that user defined and if there are some rules?
4. There are no "uint8" or "int8" in the the simpleType whose name is "allTypeKind" in the xsd file whose name is "dds-xml_type_definitions_nonamespace.xsd". But there are the definition in chapter "7.3.2.2 Basic Types" of the specification "Extensible and Dynamic Topic Types for DDS"(DDS-XTypes)

This specification lacks the XSD type definitions for the QoS extensions coming from DDSXTypes (at least DataRepresentationQosPolicy and TypeConsistencyEnforcementQosPolicy), these should be added to the DDS XML consolidated XML

The IDL specification got extended with support for uint8/int8, map, bitset/mask, but there is no mapping for this in the DDS XML specification. The DDS XML specification should also define how these new IDL types are mapped in XML

In section 7.3.2.4.4.1, the "Is equivalent to the following XML" paragraph has the wrong style. It should be "Text Body" rather than monospace.
