  We unite the one-flow-dominated-state (OFDS) argument of
\citet{MeyrandGaltierPRL12} with the one-chiral-sector-dominated-state (OCSCS)
one \citep[][]{hydrochirality} to form a nonlinear
extended-magnetohydrodynamics (XMHD) theory for the solar wind turbulence
(SWT), \textbf{ranging from the MHD- to subproton-, and even to
subelectron-scale regimes} \citep[modifying the theory
of][]{AbdelhamidLingamMahajanAPJ16}. Degenerate chiral states in
\citet{MiloshevichLingamMorrisonNJP17}'s XMHD absolute equilibria are exposed
with helical representation, to offer the basis of replacing the linear wave
(of infinitesimal or arbitrarily finite amplitudes) arguments of previous
theories with OCSDS. Possible connection of the OFDS-plus-OCSDS theory with the
local minimal-energy/stability principle is also discussed.
