public class headObject
extends X3DConcreteStatement
```
Functional summary: each X3D scene includes a head statement that can contain component, unit and meta statements. This concrete class represents an X3D head statement.

X3D statement tooltip: [X3D statement] head can contain component, unit, and author-defined meta (metadata) elements.
- Hint: design for this element matches the <head> tag in HTML.
- Warning: head is optional first child of X3D statement, and must precede the Scene statement.
- Warning: in order to pass XML validation, these contained optional statements must appear in order: first component statements, then unit statements, then meta statements.
