Return a suitable DOM implementation. The name is either well-known, the module name of a DOM implementation, or None. If it is not None, imports the corresponding module and returns DOMImplementation object if the import succeeds. If name is not given, consider the available implementations to find one with the required feature set. If no implementation can be found, raise an ImportError.
