On MediaWiki, users are able to link to sections by using anchor/fragment links like [[Article#Section]]. This functionality, however, is seriously impaired on sites with LanguageConverter, as the parser only generates a section id attribute for the unconverted title. When editors want to link to sections on these wikis, they usually have to disable the conversion or peek into the raw wikitext to know what exactly they should write for #Section.

MediaWiki should probably generate ids for all (at least "major") variants defined for a wiki and put these invisible elements somewhere next to the <h2> (or h3, h4, etc.) Deduplication among variants for each title should be done, otherwise a simple == a == would be able to generate ids like a a_1 a_2 a_3 all by itself.
