==DTD Validation==

===Children===

Children must appear as follows:

# A single, optional IS.
# A single, optional node derived from X3DMetadataObject for the ''metadata'' field.
# 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:

# A single, optional IS.
# A single, optional node derived from X3DMetadataObject for the ''metadata'' field.
# 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.
