Thanks Florent and Geert, The real motive behind this question is to implement a globally available map for all the functions of the xquery module. Any suggestions about how to implement it? May be I can put it in a different Xquery module and import it?

Avoiding side-effects when none is required will save you some (hard-to-track-down) troubles.
