DTD Validation

Children

Children must appear as follows:

1. A single, optional IS.
2. A single, optional node derived from X3DMetadataObject for the metadata field.
3. Any number of children, all of which must either be derived from X3DChildNode or else be appropriately typed Prototype nodes. They may occur in any order.

Attributes

• There is no check that the values in the bboxSize field are acceptable.

3. Any number of children, all of which must either be derived from X3DChildNode or else be appropriately typed Prototype nodes. They may occur in any order.

Attributes

• The bboxSize field is checked to ensure that the three values are acceptable.
