the behavior in 7.6 was not clean, which is why it was removed in more
recent versions. However, the latest XQUF draft (not public yet) now
provides an "updating" keyword, which can be used to invoke updating
functions
UpdatingFunctionCall ::= "updating" PrimaryExpr "(" (ExprSingle
("," ExprSingle)*)? ")"
Issue 939 will be closed as soon as we have implemented this in BaseX
[1]. As an alternative, if you set MIXUPDATES=true in BaseX 8.0, you
won't encounter any restrictions regarding the invocation of updating
and non-updating functions.
