NAMESPACE — MoQT draft-23 §9.15

The NAMESPACE message is similar to the PUBLISH_NAMESPACE message, except it is sent on the response stream of a SUBSCRIBE_NAMESPACE request. All NAMESPACE messages are in response to a SUBSCRIBE_NAMESPACE, so only the namespace tuples after the 'Track Namespace Prefix' are included in the 'Track Namespace Suffix'.

When Parameters of a NAMESPACE change, the NAMESPACE message is sent again with the updated Parameters.

NAMESPACE Message {
  Type (vi64) = 0x8,
  Length (vi64),
  Track Namespace Suffix (..),
  Number of Parameters (vi64),
  Parameters (..) ...
}
