The doc refers to "an OTHER-VARS element in `font-lock-defaults':
Variable: font-lock-syntactic-face-function
If this variable is non-`nil', it should be a function to determine
which face to use for a given syntactic element (a string or a
comment). The value is normally set through an OTHER-VARS element
in `font-lock-defaults'.
Incomprehensible. There is no "an OTHER-VARS element" described
anywhere in the doc of `font-lock-defaults' or in the link in the next
paragraph (node `Faces for Font Lock').
And there is no "OTHER-VARS" anywhere in the Emacs Lisp code, other than
a presumably unrelated (and just as undescribed) occurrence in pcase.el.

After looking through font-core.el for several seconds, I don't have any
idea, either, what this is supposed to mean. This is the full text:
The previous version was:
-Specify this variable using @var{other-vars} in
@code{font-lock-defaults}.
and
-Major modes normally set this variable with @var{other-vars} in
-@code{font-lock-defaults}.
but vc-region-history on the doc string of that variable seems to say
that it has never talked about "other-vars".
Anybody want to take a guess at what this is supposed to mean?
-- Variable: font-lock-syntactic-face-function
If this variable is non-‘nil’, it should be a function to determine
which face to use for a given syntactic element (a string or a
comment). The value is normally set through an OTHER-VARS element
in ‘font-lock-defaults’.
The function is called with one argument, the parse state at point
returned by ‘parse-partial-sexp’, and should return a face. The
default value returns ‘font-lock-comment-face’ for comments and
‘font-lock-string-face’ for strings (*note Faces for Font Lock::).

Looks like this refers to this thing described in the doc of
`font-lock-defaults':
"Further item elements are alists of the form (VARIABLE . VALUE) and are
in no particular order. Each VARIABLE is made buffer-local before set
to VALUE."
Also see the following sentences.
Maybe the docstring of `font-lock-defaults' has been changed, and a
further version used the name "OTHER-VARS".
Michael.

Yup; that makes sense. I've now adjusted the manual and added a
real-life example to help make it obvious what we're talking about.
