TOC local for specified heading and its subheadings (in HTML export)?

The #+TOC: headlines [n] local feature is really useful; I use it a lot.
How easy would it be to do a macro to generate a similar table of contents
for the subheadings of an arbitrary specified heading?  That would be an
alternative to transclusion <https://en.wikipedia.org/wiki/Transclusion>,
allowing re-use of text but with links instead of the actual text.  For UX
purposes this will sometimes be preferable to actual transclusion, e.g.,
with Angular.js.  I'm not even a cargo-cult programmer in elisp and
wouldn't have the level of skill to do this myself without spending a lot
of time.

EXAMPLE:  In the Common Draft contract form file
<http://www.CommonDraft.org>, I'd like to add a Model Confidentiality
Agreement, a Model Software Development Agreement, a Model Consulting
Services Agreement, etc.  Each of these model agreements would include
several TOC-style lists of clauses under various other headings, as shown
in the following hypothetical file excerpt:

* Model Confidentiality Agreement
  :PROPERTIES:
  :CUSTOM_ID: ConfAgrmt
  :END:

** Parties; Effective Date

This Agreement is entered into as of November 27, 2015, between ABC Ltd.
and XYZ Inc.

** Confidential Information

# ============= The next line is the desired feature: Generate a TOC list
(with links) of all subheadings in the specified heading
=====================
#+TOC: headlines 1 local ConfInfoClauses

** Notices

#+TOC: headlines 1 local NoticesClauses

* Signatures

AGREED:

ABC Ltd, by:

AGREED:

XYZ Inc., by:

* Confidential Information Clauses
  :PROPERTIES:
  :CUSTOM_ID: ConfInfoClauses
  :END:

** Confidential Information Definition
  :PROPERTIES:
  :CUSTOM_ID: ConfInfoDefn
  :END:

[text of clause]

** Confidentiality Obligation
  :PROPERTIES:
  :CUSTOM_ID: ConfInfoOblig
  :END:

[text of clause]


* Notices Clauses
  :PROPERTIES:
  :CUSTOM_ID: NoticesClauses
  :END:

​** Notices Must Be in Writing
  :PROPERTIES:
  :CUSTOM_ID: NoticesWriting
  :END:
​
​[text of clause]

** Notices by Email
  :PROPERTIES:
  :CUSTOM_ID: NoticesEmail
  :END:
​
​[text of clause]​

​I'd be happy to make a donation for this.
