 ## The content layer
 
 The content layer lives on both sides of the renderer/browser split. The content
-layer translates WebAXObjects into [AXContentNodeData], which is a subclass of
-[ui::AXNodeData]. The ui::AXNodeData class and related classes are Chromium's
-cross-platform accessibility tree. The translation is implemented in
-[BlinkAXTreeSource]. This translation happens on the renderer side, so the
-ui::AXNodeData tree now needs to be sent to the browser, which is done by
-calling the remote method [ax.mojom.RenderAccessibilityHost::HandleAXEvents()]
-with the payload being serialized delta-updates to the tree, so that changes
-that happen on the renderer side can be reflected on the browser side.

 usually forwarded to [BrowserAccessibilityManager] which is responsible for:
