We have been using MvpXslTransform to perform transforms on using a relatively complex set of XSLT files. In an attempt to improve the performance of the transforms, I am evaluating the XQSharp library.

Unfortunately, when I call ApplyTemplates to perform the transformation, the following exception is raised:

> 
> No implementation was found for extension function 'seconds' in
>  namespace 'http://exslt.org/dates-and-times' with arity 1.
> 
>

Can anyone help me to resolve this issue?
