In FIX-based markets, there is either a subscription point or a known multicast point for [tickers].
We want to be able to indicate "This Market Segment has a Tenders Ticker and you can subscribe here."
We should also support "This Market Segment has a Multicast IP address for the Tenders ticker and you can listen here."
I welcome comments on how to express this info. SO far, we have put all Market Structure in Name-Value Pairs (NVPs), which makes for simple expression.
