DTD Validation

Children

Children must appear as follows:

  1. Any number, including zero, of user defined fields.
  2. A single, optional IS.
  3. A single, optional node derived from X3DMetadataObject for the metadata field.
  4. Any number, including zero, of either:
    1. ShaderPart
    2. Appropriately typed Prototype node

Attributes

  • There are no other attributes requiring validation.

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. From zero to six nodes in total of any of the following:
    1. ImageTexture
    2. MovieTexture
    3. PixelTexture
    4. An appropriately typed Prototype

Attributes

  • There are no other attributes requiring validation.

Schematron validation

TBD
