Dear Michael
thank you for your input. I work with Saxon SA-9.1.0.6 which is not to bad with typing and not foolish strict neither... The problem is the XSLT processor allows me to use this code snippet <xsl:for-each-group select="/results/match" group-by="team"> <xsl:copy-of select="myfn:MakeTableRow(current-grouping- key(),current-group())"/> </xsl:for-each-group> with the function only without the type control... <xsl:function name="myf:MakeTableRow" as="schema- element(xhtml:tr)"> <xsl:param name="team"/> <!-- as="schema-element(res:team)" --> <xsl:param name="matches"/> <!-- as="schema- element(res:match)*" --> <tr xsl:validation="strict"> ... </tr> </xsl:function> your comment current-grouping-key() is an atomic value, not an element. You could is a solution to the problem, however not the most elegant one. Type casting would be nicer... I put the whole file in the end.
