Remarks

Represents a relative browse path.

OPC UA browse path elements are represented by UABrowsePathElement objects. Each browse path element has following data members:

ReferenceTypeId Property. The type of reference (an instance of UANodeId Class) to follow from the current node. The current path cannot be followed any further if the reference type is not available on the node instance.
ReferenceIsInverse Property. Indicates whether the inverse Reference should be followed.
IncludeSubtypes Property. Indicates whether subtypes of the ReferenceType should be followed.
TargetName Property. The browse name of the target node (an instance of UAQualifiedName Class).

The UABrowsePathElement has various constructor overloads with different combinations of these parameters. In addition, there are static methods on the UABrowsePathElement Class that allow you to easily create commonly used browse path elements:

The Create Method creates a new OPC-UA browse path element with given reference type and target name, for following in forward direction, and including subtypes.
The CreateInverse Method creates a new OPC-UA browse path element with given reference type and target name, for following in inverse direction, and including subtypes.
The CreateSimple Method creates a new OPC-UA browse path element with given target name, and specifying any hierarchical forward reference.
There are static methods for creation of browse path elements for all standard *concrete* references, taking just the target name as input. For example, the HasProperty Method creates a browse path element for following a specific HasProperty reference in a forward direction.

The created browse path elements can then be added to a UABrowsePathElementCollection Class, forming a relative path.
