The code in nsHTMLStyleSheet implements LangRule to map xml:lang into style and the code to manage its uniqueness. The change to nsGenericHTMLElement fixes the mapping of the HTML lang attribute to do cascading the way all other rule mapping does so that the cascading works correctly. The tests test that the correct style language is used for hyphenation by copying over a set of hyphenation reftests that check its basic response to languages. There are no specific tests for font selection, but font selection is known to use the same language data from style. I verified manually (see other attachments to bug) that the rule uniqueness is being managed correctly. --HG-- rename : layout/reftests/text/auto-hyphenation-1.html => layout/reftests/text/auto-hyphenation-xmllang-1.xhtml rename : layout/reftests/text/auto-hyphenation-10.html => layout/reftests/text/auto-hyphenation-xmllang-10.xhtml rename : layout/reftests/text/auto-hyphenation-1.html => layout/reftests/text/auto-hyphenation-xmllang-11a.xhtml rename : layout/reftests/text/auto-hyphenation-1.html => layout/reftests/text/auto-hyphenation-xmllang-11b.xhtml rename : layout/reftests/text/auto-hyphenation-4.html => layout/reftests/text/auto-hyphenation-xmllang-12a.xhtml rename : layout/reftests/text/auto-hyphenation-4.html => layout/reftests/text/auto-hyphenation-xmllang-12b.xhtml rename : layout/reftests/text/auto-hyphenation-1.html => layout/reftests/text/auto-hyphenation-xmllang-13a.xhtml rename : layout/reftests/text/auto-hyphenation-1.html => layout/reftests/text/auto-hyphenation-xmllang-13b.xhtml rename : layout/reftests/text/auto-hyphenation-4.html => layout/reftests/text/auto-hyphenation-xmllang-14a.xhtml rename : layout/reftests/text/auto-hyphenation-4.html => layout/reftests/text/auto-hyphenation-xmllang-14b.xhtml rename : layout/reftests/text/auto-hyphenation-1a.html => layout/reftests/text/auto-hyphenation-xmllang-1a.xhtml rename : layout/reftests/text/auto-hyphenation-2.html => layout/reftests/text/auto-hyphenation-xmllang-2.xhtml rename : layout/reftests/text/auto-hyphenation-3.html => layout/reftests/text/auto-hyphenation-xmllang-3.xhtml rename : layout/reftests/text/auto-hyphenation-4.html => layout/reftests/text/auto-hyphenation-xmllang-4.xhtml rename : layout/reftests/text/auto-hyphenation-5.html => layout/reftests/text/auto-hyphenation-xmllang-5.xhtml rename : layout/reftests/text/auto-hyphenation-6.html => layout/reftests/text/auto-hyphenation-xmllang-6.xhtml rename : layout/reftests/text/auto-hyphenation-7.html => layout/reftests/text/auto-hyphenation-xmllang-7.xhtml rename : layout/reftests/text/auto-hyphenation-8.html => layout/reftests/text/auto-hyphenation-xmllang-8.xhtml rename : layout/reftests/text/auto-hyphenation-9.html => layout/reftests/text/auto-hyphenation-xmllang-9.xhtml
