The Empty property provides alternative type syntax for groups or items when they have no data content.

When the Empty property is specified for a type and there is no data content, the Empty syntax is displayed. For example, this can be used for XML data that contains either start and end tags or an empty tag.

You can use the Empty type property instead of syntax object items to potentially improve the schema runtime processing time (during data validation).

The following options are available for the Empty property.

Default setting. Select None if you do not have an initiator, terminator, or release character.
A constant value. When Literal is selected, the Value, Ignore Case, Required, and National language sub-fields become available. You can use only one literal to indicate a zero-length data item.
