Using "xml:lang" attribute in empty element

Hi Liam,

As you know, WOFF metadata contains some empty elements (such as <vendor>, <credit>) where the end-user info is provided using attributes.
One of the LC comments submitted from the I18N WG (http://lists.w3.org/Archives/Public/www-font/2010OctDec/0105.html) brings up the issue of localization of content for these elements. With elements like credit - we can address this by adding xml:lang attributes to the parent <credits> element, but it is not clear what the result would be if the same is done for an element that doesn't have a parent.

What would be the result of e.g. adding xml:lang to <vendor> element:
<vendor xml:lang="en" name="Font Vendor" url="http://fontvendor.example.com" />
Would it have an effect on the content of the 'name' attribute? Can this be used to localize the content of the attributes (other than 'lang')?

Thank you,
Vlad
