\brief The OPC UA AttributeOperand type.
\since QtOpcUa 5.13
The AttributeOperand is defined in OPC-UA part 4, 7.4.4.4.
It has the same purpose as \l SimpleAttributeOperand but has more configurable options.
*/

\qmlproperty list<OpcUaNodeId> AttributeOperand::browsePath
Browse path to the node holding the attribute.

QtOpcUa.NodeId {
identifier: "Message"

\qmlproperty string AttributeOperand::indexRange
Index range string used to identify a single value or subset of the attribute's value.

indexRange: "0:2"

Attribute of the node \l browsePath is pointing to.

...
typeId: "ns=0;i=2041"
