Typo3 8.7 export plugin content as RSS feed - rss

Question

I want to export the contents of my extension's plugin to RSS. I have followed a number of tutorials online but none of them are working.
In my Plugin's setup-ts I have added the following (newsevents is my extension, nepi5 is the plugin within that extension)
pageNewsRSS = PAGE
pageNewsRSS{
typeNum = 9818
10 < tt_content.list.20.newsevents_nepi5
config{
disableAllHeaderCode = 1
additionalHeaders = Content-Type:application/rss+xml;charset=utf-8
metaCharset = utf-8
xhtml_cleaning = 0
admPanel = 0
debug = 0
no_cache = 1
disablePrefixComment = 1
}
}
In my template file I have the following:
<rss version="2.0">
<channel>
<title>Title</title>
<link>https://www.URLLINK.com</link>
<description>Description</description>
<f:for each="{articles}" as="article" iteration="iterator">
<item>
<title{article.titel}</title>
<description>{article.content}</description>
</item>
</f:for>
</channel>
</rss>
...when I view the page using typeNum 9818 (&type=9818), the correct action for my plugin runs, the correct data is passed through to the template, but the page is still written with HTML elements with a head tag, a body tag and within the body tag.
I'm obviously missing something major regarding templating. Any help appreciated.
I'm using a plugin in my extension because I use a Flexform to choose which items from a list I want to show.

I think your problems result from skipping a proper page templating and trying to generate the whole page in the plugin.
I would try to build a fluid page template which includes the output of the plugin. and the plugin just renders the inner loop.
