This tests mapping of lang to -webkit-locale which I think doesn't have an analogue in Firefox. One thing I'll try to do is confirm that Firefox computed language is the same as all the -webkit-locale values here, by using the CSS :lang selector or in the inspector. I don't know if there is a way to programmatically get the computed language. 575079 4 ap 2012-03-09 12:23:57 -0800 Makes sense to me. 576001 5 falken 2012-03-12 01:40:23 -0700 I found Firefox computed language has the same behavior, with one change: Firefox does not set xml:lang with setAttributeNode but does with setAttributeNodeNS. It looks like it's incorrect to use setAttributeNode for namespaced attributes, so I've revised the patch to use setAttributeNodeNS. Also, both Firefox and WebKit do an interesting thing when lang is set to the empty string. According to the HTML 5 spec, the empty string means the language is explicitly unknown, which I think means that lang shouldn't be inherited from the parent. But for the CSS :lang selector, both browsers inherit lang, while for font selection, lang is not inherited. For example, in: <div lang="ko" id="x1">x1 <div id="x2">x2</div> <div id="x3" lang="">x3</div> </div> x1 and x2 are in the font for Korean and get CSS styling for :lang(ko), while x3 has CSS styling for :lang(ko) but is not in the font for Korean. For WebKit, this happens because the :lang selector implementation climbs the DOM tree until it finds a non-empty lang. In contrast, font selection depends on -webkit-locale, which is mapped to "auto" when lang is empty, instead of being inherited. This behavior is the same regardless of whether lang is set dynamically or not. I'm thinking it's okay to keep the behavior as is, since at least it matches Firefox and setting lang to the empty string is probably an uncommon use case. (Also, I just tested IE, and it looks like it does the same thing.) 576005 6 131295 falken 2012-03-12 01:49:38 -0700 Created attachment 131295 use setAttributeNodeNS 576170 7 131295 ap 2012-03-12 09:13:06 -0700 Comment on attachment 131295 use setAttributeNodeNS > I found Firefox computed language has the same behavior, with one change: Firefox does not set xml:lang with setAttributeNode but does with setAttributeNodeNS.
