[Plugin: Google XML Sitemaps] No sitemap entries for pages of a custom post type or taxonomy

Just a brief question.

I’ve noted on a new site that the plugin doesn’t appear to generate entries for the pages of a custom post type.

Also, in the admin it will show checkbox options to include the taxonomies related to the custom post type, but it will not actually generate sitemap entries for those taxonomy pages either.

Is there perhaps a trick to that?
