Hi Alex/Eric,

Few doubts  

1) who will define streams? What is the practical use of it? Doesn't the filter will address the requirement?

2) If user is defining the streams, how to subscribe to the stream? Is stream is a mandatory parameter for subscription? 

Br,
Ambika Prasad Tripathy

RFC 5277 XPATH Filters for attribute match expressions is what I believe is achievable right now upon YANG objects.  But other PubSub  technologies like DDS (OMG) and MQTT (OASIS) can pass PubSub topic filters which are more flexible.  With this question I was hoping to leave space open for someone willing to argue for a solution here.
