Parameters
Argument | Description |
|---|---|
parent-context | Optional argument. Supplies the parent context. See also Example: Changing the Parent Context.
Parent context is the context inherited from a parent node. It determines what source data and intermediate results are available to descendant nodes. Some data-processing components, including core aggregation functions, join components, and variables, provide a parent-context parameter that allows you to influence the inherited context and consequently change the output. |
strings | This argument must be connected to a source item which supplies the actual data. The supplied argument value must be a sequence (zero or many) of xs:string. |
