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.

Attributes

• There are no limits on the acceptable range of values for the groundAngle field.
• There is no check that the groundAngle values are nondecreasing.
• There are no limits on the acceptable range of values for the groundColor field.
• There is no check that the number of groundColor values is one more than the number of groundAngle values.
• There are no limits on the acceptable range of values for the skyAngle field.
• There is no check that the skyAngle values are nondecreasing.
• There are no limits on the acceptable range of values for the skyColor field.
• There is no check that the number of skyColor values is one more than the number of skyAngle values.
• There are no limits on the acceptable range of values for the transparency field.
