Any experience how Drupal is able to meet this requirement for text parts in another language then the node language:
"3.1.2 Language of Parts: The human language of each passage or phrase in the content can be programmatically determined except for proper names, technical terms, words of indeterminate language, and words or phrases that have become part of the vernacular of the immediately surrounding text. (Level AA)" http://www.w3.org/TR/WCAG20/#meaning-other-lang-id
The recommended solution is to use the lang-attribute.
What is the best practice to realise this in Drupal in WYSIWYG-editors. And harder, in node titles and in fields?
NB: Regarding WYSIWYG editors, it can be done with CKeditor and use the attribute button, but it's seems not userfriendly (users have to fill in the language code)?
