RE: [xsl] dd mmm yyyy Date converted to number - attempt to sort using variable - unable to do so

["Michael Kay" <mhkay@xxxxxxxxxxxx>]

I would have expected to see the error message say that <xsl:sort> must be
the first child of <xsl:for-each>. Instead, Xalan seems to be trying to
evaluate the <xsl:sort> as if it were the first child, so the error message
says that the variable has not been declared. I'm afraid you'll have to
avoid using the variables, and compute the sort key directly in a single
complex expression.
