Compare these two API results (parse with "= [[Y'Z]] =" vs "= [[Y'Z]] ="): http://de.wikipedia.org/w/api.php?action=parse&text=%3D%20%5B%5BY%26%2339%3BZ%5D%5D%20%3D%0A http://de.wikipedia.org/w/api.php?action=parse&text=%3D%20%5B%5BY'Z%5D%5D%20%3D%0A In the HTML both come out as <a ...>Y'Z</a>, but the line attribute for the section comes out with the character reference included in the other output formats for the first case. The contents of the line attribute should match the <a>link text</a> in both cases.
Still valid as per today.
The line attribute of the sections is wikitext and you can see that the wikitext still contains the character reference, by also requesting the wikitext: https://de.wikipedia.org/w/api.php?action=parse&text=%3D%20%5B%5BY%26%2339%3BZ%5D%5D%20%3D%0A&prop=html|wikitext|text|sections https://de.wikipedia.org/w/api.php?action=parse&text=%3D%20%5B%5BY'Z%5D%5D%20%3D%0A&prop=html|wikitext|text|sections So this looks okay to me.
