@pragma('dart2js:tryInline')

  // TODO(41258): Delete this assertion after forcing strong mode.
  // Protect [name] against string conversion to "null" or "undefined".
  // [namespaceURI] does not need protecting, both `null` and `undefined` map to `null`.
  assert(name != null, 'Attribute name cannot be null');
