Text replacement - "[http://www.w3.org/TR/xpath-functions-31" to "[https://www.w3.org/TR/xpath-functions-31"
=Non-Determinism=
In [httphttps://www.w3.org/TR/xpath-functions-31/#dt-deterministic XQuery], ''deterministic'' functions are “guaranteed to produce ·identical· results from repeated calls within a single ·execution scope· if the explicit and implicit arguments are identical”. In BaseX, many extension functions are non-deterministic or side-effecting. If an expression is internally flagged as non-deterministic, various optimizations that might change their execution order will not be applied.
