Detailed Description

Represents base class of all attribute expressions.

Represents base class of all attribute expressions.

Note:

Currently there is only support for attribute [position()=n] (whereas n denotes a (numeric) position of an item in a sequence). This information is used internally to determine that only the first item in a sequence needs to be kept.
