> Hi All Testers :)
>
> I prepared an example storage file. It contains FOUR lookup infos:
>   three MAs (Pionier, ACAD and test one) and one Topology Service
>   (without data elements).
> All together have 202 interfaces (data elements)
>
> The file is too small for testing, but perfect for developing XQueries.
>
> File is attached to this e-mail.
>
> To all XQueries namespaces declaration instructions should be added:
