XPath 3.1 Functions and Operators

Notes on the Saxon implementation

Available from Saxon 9.5, provided XPath 3.0 is enabled. Streaming for the has-children() function is implemented from Saxon 9.7; specifically, a call on has-children() is now motionless, so that the call does not consume the content. This means, for example, that the call can appear as a predicate in a match pattern. The implementation uses a tiny amount of look-ahead in the parsing pipeline.
