Detailed Description

Represents an XQuery attribute for a single XPath path step of the form [position()=n].

Represents an XQuery attribute for a single XPath path step of the form [position()=n] (whereas n denotes a (numeric) position of an item in a sequence), which takes a position n as argument.

Note:

The information [position()=n] or [position()=1] respectively is only used internally to determine that only the first item in a sequence needs to be kept.
