[x3d-public] X3D XML Encoding lacks support for NULL nodes

[Holger Seelig]

The X3D XML Encoding lacks support for NULL nodes.

Althought it is possible with X3D Classic Encoding to write:

Script {
   inputOutput MFNode matrix [ USE A, NULL, USE B, NULL, USE C ]
}

it is not possible to do this in X3D XML Encoding, and therefore there 
should probably something like a NULL-tag <NULL>.

<Script>
   <field accessType='inputOutput' type='MFNode' name='matrix'>
      <Script USE='A'/>
      <NULL/>
      <Script USE='B'/>
      <NULL/>
      <Script USE='C'/>
   </field>
</Script>
