Functional summary: the meta statement provides metadata information about a scene, where name and content attributes provide attribute=value metadata pairs. This concrete class represents an X3D meta statement.

X3D statement tooltip: [X3D statement] The meta statement provides metadata information about the X3D model and uses the same definitions as HTML's meta tag. The name and content attributes together define attribute=value metadata pairs.
