This transformer accepts any feature.
All processed features are output through this port.
Click the browse button to display the list dialog. Select the attributes that you want to keep on the feature. The unchecked attributes will be removed, except for any fme_* attributes.
After you connect this transformer, click the Browse button and select the lists to keep.
Note that if you select to keep a list, your selection will include any list attributes or nested lists. For example, if you select to keep a list called

then list{}.attr or list{}.sublist{}
will also be kept.
