While slighty off-topic, my goal was to reduce the final HTML file size. The more pages, the larger ToC so the size of the complete set grows exponentially. If ToC is extracted and then just linked in every HTML page, it reduces the total size significantly. If documentation is shipped together with desktop app in the form of installer, it is better to keep it as small as possible.

Sorry not being precise, that mentioned XSLT transformation (for my DocBook XML) is performed once off-the-browser, producing linked static HTML pages (and also JSON with the file hierarchy). I wanted to emphasize that generating JSON can be, in specific cases, nicely integrated into current generating workflow (the file structure is already available in DocBook XSL stylesheets for other purposes so it was quite easy to reuse it for generating JSON for ToC).
