An index and its documents

robots.txt declares two sitemaps: the index, which points at eight further documents, and a standalone sitemap listing pages the index never mentions.

What the index points at

• sitemap-pages.xml — an ordinary urlset
• sitemap-blog.xml — timestamps down to the minute
• sitemap-images.xml — image entries and hreflang alternates
• sitemap-text.txt — the plain text format, one URL per line
• sitemap-archive.xml.gz — gzipped, and only there once the generator has run
• sitemap-nested-index.xml — an index inside an index, which the protocol forbids
• sitemap-missing.xml — declared, never uploaded, answers 404
• index.html — declared as a sitemap, and in fact this page

Pages

• About
• Services
• Contact
• Gallery — the page the image sitemap describes
• Blog

The pages under notes/, nested/ and legal/ are listed in a sitemap and linked from nowhere, which is the only way to reach them.
