Attributes:

children(node)

Returns an iterator of child nodes.

Example:
```
<c:forEach var="node" items="${wp.selectionModel.children[wp.identification[wp.selectionModel.selected]]}">
    ${node}<br>
</c:forEach>
```
Parameters:
- node
  
  Identifiable, or NavigationNode object to look up the children; it must not be null.
Returns: An iterator with NavigationNode objects; it is never null.
