B.1.2 Introduction

An XML schema defines the syntax of an XML tagset using an XML-based grammar as specified in 2.[SCHEMA].

The X3D Schema has sufficient expressive power to:

express scenes that may include any or all aspects of the functionality specified in ISO/IEC 19775-1;
validate correct naming and usage of elements (i.e., X3D nodes);
identify correct naming of corresponding attributes (i.e., X3D fields); and
validate correct types and ranges of attribute values.

The X3D DTD does not have sufficient expressive power to selectively validate content according to the defined profiles.

Revised: 16 September 2004

Design summary:

- Schemas define XML tagsets in depth using a native-XML format.

- Schemas are an alternative to Document Type Definitions (DTDs).

- This X3D Schema matches the functionality of the X3D DTD and

provides significant further capabilities, including strong type

checking of both node and attribute values.

- An XSLT stylesheet can be applied to this schema to autogenerate

source code for the Scene Authoring Interface (SAI), documentation

of node lists, etc.

Design patterns:

- X3D nodes implement X3D node types and are represented by XML elements.

- X3D non-node fields are represented by XML attributes using field types.

- X3D field types are represented by XML Schema (xsd) simpleTypes.

- XML Schema list types are used to augment XML Schema simple types, to

create arrays of X3D base types (integerList etc).

- X3D node types (X3DGroupingNode etc.) are represented by Schema complexTypes.

- X3D node types match the interface hierarchy, capture strong typing of node,

relationships, and collect common attributes shared by nodes. These

features provide functional consistency between scene graph content and the

Scene Authoring Interface (SAI) application programming interface (API).

- XML Schema xs:group element definitions provide child-node content models,

since complexTypes can't be used as references to unnamed element children.

<xs:simpleType name="BoundingBoxSize">

<xs:annotation>

<xs:appinfo>X3DBoundedObject indicates that bounding box values can be provided 
(or computed) for this node and any children. Bounding box values approximate 
the volume of a containing box in the current coordinate system. Bounding box 
values can optionally be provided to (or calculated by) 3D browsers. Bounding 
box values are hints that can improve performance by allowing browsers to 
inexpensively cull geometry, thus avoiding the computational cost of trying to 
drawing shapes when they are outside of the current view. BoundingBoxSize 
dimensions are non-negative values. Default value (-1 -1 -1) indicates that no 
bounding box size has been computed.</xs:appinfo>

<xs:appinfo>ContainedNodeLabel tags help distinguish between the different uses 
of node siblings that might otherwise share the same node type.

These tags are labels in the scene graph, not instantiable nodes.

Because these tags do not need to be instantiated as scene graph nodes, they do 
not have DEF or USE values like X3DNodes.

ContainedNodeLabel tags are sometimes referred to as &quot;wrapper tags.&quot; 
Note that ContainedNodeLabel tags are not needed when node siblings have 
different types. Thus &quot;wrapper tags&quot; are not needed for most child 
nodes in the VRML 97 node set.</xs:appinfo>
