With the new Vulkan dynamic rendering, how to clear attachments outside of CmdBeginRendering?

It is sometimes necessary to clear part or all of an attachment during a rendering sequence.

Render passes and frame buffers had an array of attachments identified by index. CmdClearAttachments was used to clear a rectangle during rendering. CmdClearColorImage and CmdClearDepthStencilImage also exist, but these are used outside render passes and also don't support rectangle clearing.

What is the equivalent operation with dynamic rendering?

Dynamic rendering's vkCmdBeginRendering creates a render pass instance, which has a sequence of attachments. vkCmdClearAttachments clears attachments of a render pass instance.

Dynamic rendering is not a different kind of rendering; it's just a shortcut to what already exists.
