  Bilingual sitemap: every page is published as an English/Chinese pair and each
  <url> carries its own three xhtml:link alternates (en, zh-CN, x-default).

  Pages covered: 30 pairs = home, products, about, contact + 4 application pages
  + 22 product pages, in both languages (60 <url> entries).

  To add a page: copy the pair of <url> blocks and update <loc>, all three
  href values and <lastmod>. Home is written as https://www.sdrcmz.com/ and
  https://www.sdrcmz.com/zh/ - never with index.html.
