How import stylesheet script?

Hi

I am using <msxsl:script> a lot in my stylesheets and Im looking for a way
of sharing one set of script methods (perhaps an assembly?) between all my
stylesheets rather than having copies of the same code. It would be nice if
the application itself could handle these "extensions" and if any stylesheet
on this app could use them only by implementing its namespace. Is this
possible somehow? I'm having trouble finding info about this.
