1. Create a new data source (/admin/config/search/simplesitemap/super-extras/data-sources/add).
2. Fill in a "Label" and select a "Sitemap" to include this data source in.
3. Under the "XML source" field, paste in valid sitemap XML markup where at least one element contains a
value - e.g.,
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="/sitemap_generator/default/sitemap.xsl"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:image="http://www.google.com/schemas/sitemap-image/1.1">
