XSL stylesheet issue (newbie)

Hello everyone,

The stylesheet below is supposed to add a unique 'id' attribute named
'tocref001', 'tocref002' etc. to all <h2>, <h3> and <p class="rn_heading">
elements which are descendants of an element with an 'id' attribute named
'rn_release_notes'. The script runs without any errors, but does not add any
IDs.

I admit that I have little to no knowledge of XSLT. ChatGPT was my friend. But
I have created a small HTML file and an XSL stylesheet with slightly simpler
XPath expressions which works fine. But it does not work with a more complex
HTML file. I have attached such a file to this message. A colleague who is a
software developer tried to debug the stylesheet with Visual Studio, but
without success.

The purpose of this script, when finished, is to create a Table of Contents
for an HTML file. The current state of it is only to add hyperlink targets to
the relevant headings.

Any help is greatly appreciated.
