{{- /*
The reference used to create this template is at https://cyber.harvard.edu/rss/rss.html.
The template does miss out on certain things which I put it on a list for those who are interested:
   * Since there's no standard for multiple authors (with <author>) in the <item> element, I decided it would be best to leave it out for now.
   * The name was left out for certain elements that requires an email address (like <managingEditor>, <webMaster>, or <author> in the <item>.
   * <item:guid> is a permalink to the HTML post.
   * No <item:enclosure>.
   * <item:description> contains the whole post; if you want to change it to <item:content:encoded> and make <item:description> a summarized version, refer to https://www.rssboard.org/rss-profile and change the description tag with `.Summary | safeHTML`.
