Body:
| (Value*, Query*, AuditRecord?, Signature?, Annotation* ) |
Attributes:
| ItemOID | oidref | Reference to the ItemDef. | |
| TransactionType | (Insert | Update | Remove | Upsert | Context) | (optional) | The TransactionType attribute need not be present in a Snapshot document. |
| IsNull | (Yes) | (optional) | IsNull is a flag to signify that an item's value is to be set to null. If the Value attribute is set, IsNull must not be set. If IsNull is set, the Value attribute must not be provided. In the interest of creating non-verbose XML instances, one should not use ItemData elements with IsNull set to "Yes" to indicate uncollected data. The better practice is to transmit only collected data. |
Contained in:
The ItemData element is used for transmission of the clinical data for an item. The model does not support repeating items within a single item group.
The ItemOID is used to identify a particular item definition. This value uniquely identifies an Item within the containing ItemGroup.
The referenced ItemDef defines the DataType of this item. The Value attribute string must obey the rules for that format of data listed in the Data Formats section. For text, string, integer or float datatypes, it must be possible to store the item value within the Length constraint defined in the ItemDef.
