So far as I can tell, org-mode currently allows heading numbering in only
one style (1, 1.1, 1.1.1, etc.). For HTML export, I'm interested in having
the heading numbering be configurable on a per-subtree basis, along
something like the following lines for a hypothetical consulting-agreement
contract (indentation is for convenient reading only). This is for my Common
Draft <http://www.CommonDraft.org> contract terms and conditions project
--- I'd like to be able to arrange the trees in an arbitrary order and have
the top-level headings start with prefixes and heading numbers instead of
heading numbers alone.
This can be done in a very kludgy fashion with CSS (see below), but doing
it in org-mode would be far preferable for several reasons.
I'd be happy to pay an honorarium, or make a donation, of USD$100-$200 for
the appropriate elisp code that I could include in the relevant file(s).
I'd want the elisp code to be open-sourced, and at least minimal
documentation, so that it could be made a candidate for possible inclusion
in a future org-mode release.
Here's an example of the desired org-mode code:
===BEGIN===
* Services
:PROPERTIES:
:CUSTOM_ID: SVC
:CUSTOM_PREFIX: t
:END:
# ======== NOTE THE :CUSTOM_PREFIX: property above =========== #
** Statements of Work
[properties and text omitted]
*** Written Statements of Work Required
[properties and text omitted]
# =========== AN ARBITRARY NUMBER OF SUBHEADING LEVELS BENEATH THE TOP
LEVEL ============= #
*** Changes Must Be in Writing
[properties and text omitted]
** Billing Rates
[properties and text omitted]
** IP Ownership
[properties and text omitted]
* General Provisions
:PROPERTIES:
:CUSTOM_ID: GP
:CUSTOM_PREFIX: t
:END:
** Amendments
[properties and text omitted]
** Notices
[properties and text omitted]
===END===
I'd like for the resulting HTML export to be something like the following:
SVC Services
# ======== NOTE THAT THERE'S NO HEADING /NUMBER/ FOR THE TOP-LEVEL HEADING,
JUST THE PREFIX ========== #
SVC-1 Statements of Work
[properties and text omitted]
# ======== PREFERABLY THE SEPARATOR IN "SVC-1" COULD BE CONFIGURED AS A
HYPHEN, A PERIOD, A COLON, A FORWARD SLASH, ETC. ============= #
SVC-1.1 Written Statements of Work Required
[properties and text omitted]
SVC-1.2 Changes Must Be in Writing
[properties and text omitted]
SVC-2 Billing Rates
[properties and text omitted]
SVC-3 IP Ownership
[properties and text omitted]
GP General Provisions
GP-1 Amendments
[properties and text omitted]
GP-2 Notices
[properties and text omitted]
I've played with doing this in CSS --- a suboptimal solution would be to:
1. set the :UNNUMBERED: property to non-nil
2. define separate CSS div classes for each top-level heading (e.g., SVC
and GP in the examples above)
3. for each top-level heading in question:
1. use the :HTML_CONTAINER_CLASS: property to specify the div class
for that top-level heading
2. for each subheading level in that div class, use the
psuedo-element ":before" to add the appropriate prefix and counter
Apart from being kludgy, doing it this way (in CSS) would eliminate
org-mode's ability to produce automatic cross-referencing during export.
Also, the heading numbers wouldn't transfer over when copying and pasting
from HTML to a Word document, which is an important user feature.
In case it matters, I run the 2016-07-25 release of org-mode on Emacs
25.1.50 (9.0) with the most recent update of Mac OS X El Capitan. I know a
little about elisp and have cobbled together a few simple functions for my
own use, but I'm far from being even minimally competent at it.
Any ideas for an org-mode elisp solution?
Thanks in advance,

Possibly not what you're asking but, you can ignore CUSTOM_PREFIX
property altogether and use a headline filter to do what you want.
(defun my-heading-prefix-filter (heading backend info)
"Prefix every heading and sub-heading with custom ID.
Skip one level of numbering."
(when (org-export-derived-backend-p backend 'html)
(let ((internal-ref
(and (string-match "\\`.*id=\"outline-container-\\(.+?\\)\"" heading)
(match-string 1 heading)))
(id (and (string-match "\\`.*\n<h[0-9]+ id=\"\\(.*?\\)\">" heading)
(match-string 1 heading))))
;; When there is no custom ID, id attribute contains the
;; internal reference. So we check if there is a custom ID which
;; is going to become the prefix of all headings.
(unless (equal internal-ref id) ;No custom ID
(let ((s 0))
(while (string-match
"\\(<h.+?>\\)\\(?:.*?<span class=\"section-number-[0-9]+\">\\(.+?\\)</span>\\)?"
heading s)
(setq s (+ (match-end 0) (length id) 1))
(setq heading
(cond
;; Unnumbered heading.
((not (match-end 2))
(replace-match (concat "\\1" id " ") nil nil heading 1))
;; Top level heading. Ignore numbering.
((string-match-p "\\`[0-9]+\\'" (match-string 2 heading))
(replace-match id nil nil heading 2))
;; Sub-headings. Skip first number.
(t
(let ((numbers
(save-match-data
(split-string (match-string 2 heading) "\\."))))
(replace-match
(concat id "-" (mapconcat #'identity (cdr numbers) "."))
nil nil heading 2))))))
heading)))))
(add-to-list 'org-export-filter-headline-functions
'my-heading-prefix-filter)
custom ID is used to prefix every heading with its value. Of course, it
means that every heading with a custom ID is expected to follow this
pattern, so you cannot toggle the feature subtree wise. Anyway that's
a starting point.

Many thanks, Nick -- an interesting approach, but it's not a good fit for
what I need.
Another approach would be possible if org-mode had a way of including
arbitrary attribute text in HTML exports of headings. This would enable
use of the CSS attr()
<https://developer.mozilla.org/en-US/docs/Web/CSS/attr>functionality,
combined with the ::before pseudo-element and counters. I've tested out
the following in HTML; it seems to work for what I need:
==BEGIN HTML SNIPPET==
<style>
body { counter-reset: section-counter; }
h2 { counter-reset: sub-section-counter; }
h3 { counter-reset: sub-sub-section-counter; }
h2::before {
counter-increment: section-counter;
content: attr(CDArticlePrefix) "-" counter(section-counter) " ";
}
h3:before {
counter-increment: sub-section-counter;
content: attr(CDArticlePrefix) "-" counter(section-counter) "."
counter(sub-section-counter) " ";
}
h4:before {
counter-increment: sub-sub-section-counter;
content: attr(CDArticlePrefix) "-" counter(section-counter) "."
counter(sub-section-counter) "." counter(sub-sub-section-counter) " ";
}
</style>
<h2 CDArticlePrefix="DEFN">Definitions</h2> <!-- NOTE THE "CDArticlePrefix"
ATTRIBUTE -->
<h2 CDArticlePrefix="SERV">Consulting Services</h2>
<h2 CDArticlePrefix="PMT">Payment Terms</h2>
<h2 CDArticlePrefix="GPR">General Provisions</h2>
==END HTML SNIPPET==
Unfortunately, org-mode does not seem to be able to include the
CDArticlePrefix="DEFN" attribute text in headings, as opposed to in divs.
I appreciate the response.
