 # Members and classes from the dom that should be removed completely from
 # dart:html.  These could be expressed in the IDL instead but expressing this
 # as a simple table instead is more concise.
 # Syntax is: ClassName.(get\.|set\.)?MemberName
 # Using get: and set: is optional and should only be used when a getter needs
 # to be suppressed but not the setter, etc.
 # TODO(jacobr): cleanup and augment this list.
