Description

This step is modeled on the p:xquery step, but for XPath.

The context item is set by the source port. If more than one document appears on the source port, the context item is undefined and all of the documents from that port form the default collection.

Any parameters passed are used to configure the in-scope variables for the expression.

The version must be “3.1”, if it is specified.
