<!-- The same site is served on three domains: www.seadev.uk (English, United
     Kingdom), www.seadev.org (English, international) and www.seadev.fr
     (French). Two English URLs cannot share the bare 'en' code, so the UK one
     is qualified as en-GB and the .org carries generic English plus x-default.
     Every URL lists all alternates, itself included, as reciprocity requires.
     All three domains must be verified in the same Search Console account for
     this cross-domain sitemap to be honoured. -->
