Right. Or `/*/html:html/` in this case since there's a wrapper element.

`//*/@xml:lang` is a fallback, and I think it's better than simply defaulting to english if there's no `meta/@dc:language` or `html/@xml:lang`. Or do you mean it would be better to use `/*//*/@xml:lang`? (I suppose the element selector could be dropped as well, and just use `//@xml:lang` or `/*//@xml:lang`).
