Text Inheriting its Programmatic Language from an Element	text-inheriting-language	true	true	DOM tree Accessibility tree CSS Styling

The text inheriting its programmatic language from an element E is composed of all the following texts:

• text nodes: the value of any text nodes that are visible or included in the accessibility tree and children of an element inheriting its programmatic language from E;
• accessible text: the accessible name and accessible description of any element inheriting its programmatic language from E, and included in the accessibility tree;
• page title: the value of the document title, only if E is a document in a top-level browsing context.

An element F is an element inheriting its programmatic language from an element E if at least one of the following conditions is true (recursively):

• F is E itself (an element always inherits its programmatic language from itself); or
• F does not have a non-empty lang attribute, and is the child in the flat tree of an element inheriting its programmatic language from E; or
• F is a fully active document element, has no non-empty lang attribute, and its browsing context container is an element inheriting its programmatic language from E.
