On the other hand the following construction is completely legal and the annotated-function is dynamically created: · declare function mySpace:constructor( $a, $b, ….) { %myAnnotation( ‘wishThisWasAvariable-InsteadOfAliteralValue’) function ( $f ){$f( $a, $b, ……..)} } ; The function and probably so also its annotation is created dynamically. So it needs a little feasibility-study . Is there room for a little feasibility-study ;-) ( I know capacity) Kind Regards, Rob Van: [email protected] [mailto:[email protected]] Namens Ghislain Fourny Verzonden: donderdag 23 juli 2015 16:56 Aan: Rob Stapper CC: [email protected] Onderwerp: Re: [xquery-talk] annotations in function-declarations Hi Rob, Just off the top of my mind, I would expect some challenges with respect to dynamically vs. statically known information. With a literal, all annotations are known statically. With a variable, this is no longer the case. This may have unexpected implications for function type checking, etc. I hope it makes sense.

So actually function-creation is also during processing. Is this something that W3C sees as a useful enough addition and is it feasible within the given capacity?
