X3D node tooltip: (X3D version 3.2 or later) [X3DLayerNode] LayoutLayer is a Grouping node that can contain most nodes. LayoutLayer content is clipped by the specified viewport node.
- Hint: insert a Shape node before adding geometry or Appearance.
- Warning: better functional description needed in X3D specification.
Package hint: This org.web3d.x3d.jsail concrete class is used for implementing a standalone X3D object as a Plain Old Java Object (POJO). If you are writing Java code for use inside an X3D Script node, compile separate code using only the org.web3d.x3d.sai package instead.

    Assign String value to inputOutput SFString field named USE.
    
    Tooltip: USE means reuse an already DEF-ed node ID, excluding all child nodes and all other attributes (except for containerField, which can have a different value). Hint: USE references to previously defined DEF geometry (instead of duplicating nodes) can improve performance. Warning: do NOT include any child nodes, a DEF attribute, or any other attribute values (except for containerField) when defining a USE attribute.

    Note: each USE node is still an independent object, with the USE value matching the DEF value in the preceding object.
    
    Warning: invoking the setUSE() method on this node resets all other fields to their default values (except for containerField) and also releases all child nodes.
    
    Warning: no other operations can be performed to modify a USE node other than setting an alternate containerField value.
