Don't you mean XSLT 2.0

    Dimtre> Compare to the strict type definition in Haskell:

    Dimtre>         map :: (a -> b) -> [a] -> [b]


I see what you mean - for f:map you currently have:

    
    <xsl:function name="f:map" as="item()*">
      <xsl:param name="pFun" as="element()"/>
      <xsl:param name="pList1" as="item()*"/>

whereas what you want is:

    
    <xsl:function name="f:map" like="pList1">
      <xsl:param name="pFun" as="element()"/>
      <xsl:param name="pList1" as="item()*"/>

which is not valid XSLT 2.0.
And I guess it's probably too late to have such a proposal considered.
