If I take the following (valid) XHTML document and try to render it as a JSF
page with facelets, the nesting of lists is for whatever reason wrong, the
second heading is indented and displayed as part of the first list. It works as
soon as I remove the xmlns:kiwi attribute from the link (which is, however,
valid XHTML). Namespace declaration in e.g. ui:composition seems to work,
though, but since my XHTML is generated automatically as canonicalized XML, I
consider this a serious bug nonetheless.
