Your question is related to the attached XQuery issues which are in the current Working Draft [1].  The WG continues to work on these issues but as yet has not finalized its position.

74. xquery-module-syntax: Module syntax 

Locus: xquery Cluster: module-semantics Status: active 
Originator: XQuery Editors 


The definition and syntax of a query module are still under discussion in the working group. The specifications in this section are pending approval by the working group. 

Future versions of the language may support other forms of query modules, such as update statements and view definitions. 

75. xquery-import: Importing Modules 

Locus: xquery Cluster: module-semantics Status: unassigned 
Originator: XQuery Editors 


The means by which a query module gains access to the functions defined an an external function library remains to be defined.

Should xmlns only be respected for construction, Xquery expressions but not functions, or also functions?

Subject: Mathematical functions




is it possible to use mathematical functions in XQuery using a standardised library with a dedicated namespace ?

If not, what is the best way to use functions not defined in the built-in functions core library without defining them

into the XQuery itself ? Defining sin or tan using Taylor series may be very inefficient.


Best regards.
