Re: Pattern matching error in xsl:key

Ihe,

This is a type casting error (see e.g. https://docs.basex.org/wiki/XQuery_Errors#Type_Errors ) and I am pretty sure you could make the life for Saxon easier if you would add some typing information.

In the first place I assume you want 

 <xsl:param name="source" select="'4.0'" as="xs:string"/>
 <xsl:param name="target" select="'4.1'" as="xs:string"/>

It may work without the as attribute, but the apostrophes should be there in any case.
