[SGF] A standard about the meaning of `SGF markups`?

[HackYardo]

https://www.red-bean.com/sgf/user_guide/index.html SGF has some markups, but no their meanings. For example, which sgf markup should be used in order to represent the final_status_list seki of the GoTextProtocol? TR, CR, or SQ? Is there a standard tells that: TR = key stones SQ = a group of stones CR = seki stones DD = ownership (territory or area) ?

There is no such standard. It is up to the SGF comments or external text accompanying the diagram to explain the meaning of the various markup shapes. E.g. "The 🜂 stones are in trouble" or "The marked stones are in atari".

Thank you @goodger very much.
