Why is ex_generate_origin_combo_sitemap() assigned to two different hooks AND register_sitemap()? Shouldn't register_sitemap() alone suffice? Is this a backwards compatibility thing?

Yes - only register_sitemap() is required. Lines like add_action( "wpseo_do_sitemap_CUSTOM_KEY", '....'); are redundant as register_sitemap() already adds these actions, see line 165 of the Yoast source class.

Just added two new gists as a more comprehensive examples. All in one file, including writing sitemap <url> tags with images. Don't have all the extra "practitioner" cruft.

I am getting 404 - page not found in my staging environment after generating custom sitemap using this code. Please suggest a fix for this. I have already saved permalink, cleared all kind of cache but still not working.
