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
construct an element and give it a type by validating it, but I
suspect
that's not what you want to do.
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.
Thanks again
Leo
