Setting up user defined texinfo headlines using outline-heading-alist |

I am running GNU Emacs 27.1 build as x86_64-pc-linux-gnu with GTK+ Version
3.22.30
and cairo version 1.15.10.
I have a texinfo file (test.texi attached) where I defined some additional
sectioning
commands (e.g. @usec, @usebsec). I customarily switch on outline-minor-mode to
see the
headings. outline-minor-mode gives the possibility to define my own set of
headings
(e.g. @usec, @usebsec) by setting up "outline-heading-alist".
With the default settings I get
@node uchapter-amcoh
@unnumbered 6 @ Ameliorating Waveform Coherency...
Have modified my init file with the following code that resets
"outline-heading-alist"
to include @usec, @usebsec as headings in addition to @unnumbered
(defvar texinfo-hdlevels
'( ("@chapter" . 2)
("@section" . 3)
("@subsection" . 4)
("@subsubsection" . 5)
;; --------------------------------------------------
("@unnumbered" . 2)
("@unnumberedsec" . 3)
("@unnumberedsubsec" . 4)
("@unnumberedsubsubsec" . 5)
;; --------------------------------------------------
("@appendix" . 2)
("@appendixsec" . 3)
("@appendixsubsec" . 4)
("@appendixsubsubsec" . 5)
;; --------------------------------------------------
("@majorheading" 2)
;; --------------------------------------------------
("@chapheading" 2)
("@heading" 3)
("@subheading" 4)
("@subsubheading" 5)
;; --------------------------------------------------
("@uchap" . 2)
("@usec" . 2)
("@usubsec" . 3)
("@usubsubsec" . 4) ))
(setq-local outline-heading-alist texinfo-hdlevels)
I was expecting to see the following
@node uchapter-amcoh
@unnumbered 6 @ Ameliorating Waveform Coherency
@usec @value{seclb} Abductive Reasoning...
@usec @value{seclb} Parsimony over Complexity...
@usubsec @value{seclb} The Claerbout Conjecture...
@usec @value{seclb} Correlograms in Helioseismology...
@usubsec @value{seclb} Solar Magnetic Cycle and the Interface Dynamo...
But I am only seeing
@node uchapter-amcoh
@unnumbered 6 @ Ameliorating Waveform Coherency...
