public static function SitemapGeneratorBase::isMultilingualSitemap in Simple XML sitemap 8.3

Determines if the sitemap is to be a multilingual sitemap based on several factors.

A hreflang/multilingual sitemap is only wanted if there are indexable languages available and if there is a language negotiation method enabled that is based on URL discovery. Any other language negotiation methods should be irrelevant, as a sitemap can only use URLs to guide to the correct language.

Return value

bool
