| Children | This node's child nodes. (Inherited from PlaceholderTemplateNode) | 
| ContextType | The data type this placeholder emits during expansion. (The type emitted by the final level.) | 
| IsLeaf | True if this node cannot contain children. (Inherited from PlaceholderTemplateNode) | 
| Levels | The placeholder's children cast as levels. |

| AppendChild | Appends a child node to this node's children. (Inherited from PlaceholderTemplateNode) |
