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, including none, of nodes derived from X3DChildNode or Prototype nodes in any order.

Attributes

There is no validation of the numerical values of the bboxCenter or bboxSize fields. Neither is there any validation of the number of values.

Schema 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, including none, of nodes derived from X3DChildNode or Prototype nodes in any order.

Attributes

• The bboxCenter field accepts a triplet of numerical values.
• The bboxsize field accepts either three positive values or the triplet -1 -1 -1.
