# This domain exposes DOM read/write operations. Each DOM Node is represented with its mirror object
# that has an `id`. This `id` can be used to get additional information on the Node, resolve it into
# the JavaScript object wrapper, etc. It is important that client receives DOM events only for the
# nodes that are known to the client. Backend keeps track of the nodes that were sent to the client
# and never sends the same node twice. It is client's responsibility to collect information about
# the nodes that were sent to the client.<p>Note that `iframe` owner elements will return
# corresponding document elements as their child nodes.</p>
