:-)  I think what I meant was, looks like (org-export-read-attribute
:attr_html src-block) RETURNS a plist.  But that doesn't seem to be quite
true, if I'm understanding properly what a plist is.

Instead it returns a list of this form:
(:code_attribs data-external-libs="https://cdnjs.cloudflare.com/ajax/
libs/jquery/3.1.1/jquery.js" data-other="other" :class some class list)

 Access to the :properties only seems reliable through
(org-export-read-attribute :attr_html src_plock :propname), which returns
what should be an odd list of symbols (?) as a string. Again, it seems
somewhat mysterious to me.

UPDATE: despite the tentative solution seen below, I guess maybe the
#+ATTR_XXX attributes are not intended for iteration as I describe, but
instead each such attribute should have a well-specified function that the
exporter knows about.  If I'm adding attributes -- and it turns out that
ox-reveal can interpret a :code_attribs attribute that I hadn't known about
-- then I feel like I should structure them in an expected way.  I haven't
found documentation about the best practice here and would definitely
appreciate further pointers.

ah, ok, thank you.   Someday I hope I really understand list objects and
how to transform them.  I think part of the problem is that, unlike in some
other languages, programming effectively requires a proper understanding of
*what the objects are that you're manipulating*, and I'm just a bit too
stupid to learn this effectively on my own.

And then, if I want to transform this into:

This is the method i'm using, but for me it's veeeeerrrrry slow.
