valrng and invalrng specific child nodes

ddi_item() is the counterpart to range; used to encode individual values. This is an empty element consisting only of its attributes. The "UNITS" attribute permits the specification of integer/real numbers. The "VALUE" attribute specifies the actual value.

ddi_key() is the range key. This element permits a listing of the category values and labels. While this information is coded separately in the Category element, there may be some value in having this information in proximity to the range of valid and invalid values. A table is permissible in this element.

Value

A ddi_node object.

Shared and complex child nodes

• ddi_notes()
