RE: [xsl] Is it possible to create xsl:sort from input parameters using XSLT 2.0 (Saxon)?

["Huditsch, Roman \(LNG-VIE\)" <Roman.Huditsch@xxxxxxxxxxxxx>]

Hi Nick,

As far as I can tell, it is not possible to generate <xsl:sort>
instructions that way, since the <xsl:sort>s in your example would only
apply to your inner for-each loop.
Is a two-pass solution also suitable for you?

best regards,
Roman
