Hi, If "select" is a local action in the UA to choose a "line" to use and this determines the what is in the from header then this is I believe out of scope for this draft which should not mention selecting lines or AOR's as this is a different feature. The SA draft is limited to sharing appearances of the same AOR.
Also if "select" is a local action at the UA that is just UI behaviour then probably no need to mention it at all.
