added and using that as a marker for xterm(1)-like, assume that if the terminfo(5) entry already has XT or the clear capability starts with CSI then the terminal is VT100-like and it should be safe to send DA requests. The DA responses trigger additional features being added. This is all to detect extensions if terminfo(5) is wrong or inadequate. If it fails, tmux will just fall back to using the capabilities in the terminfo(5) entry alone.
