Inspired by a blog post I read recently [1] I wanted to see how feasible
it would be to add an RSS stylesheet to the feeds that Django's
syndication framework generates.

In XML, that means adding a "processing instruction" (`<?xml-stylesheet
href="/rss.xsl" type="text/xsl"?>`) right after the start of the document
(`<?xml version="1.0" encoding="utf-8"?>`) but before the root node. It
turns out the syndication framework doesn't have the right hooks to make
this easy.

I would like to suggest adding support for a new optional argument that
would let users specify a path to a stylesheet URL. Or if that's
considered too specific/niche of a feature, then at least add a hook to
let users add the behavior without rewriting methods (for example by
moving `handler.startDocument()` out of `RssFeed.write()` and into a new
method).

Comment:

Hi Baptiste, I am not very knowledgeable in RSS feeds, but this feels
related to #12978 and certainly the "motivation" behind it feels very
similar.
I'm going to mark this as a duplicate of #12978 but if you disagree,
please let me know 👍

Hi,

Sorry my mistake. I had searched on trac for an existing ticket but not
well enough apparently (I think i just did a keyword search on "rss" in
the summary).

This ticket is an exact duplicate, and my PR is even really similar to the
14 year old patch that was already attached 😅
