<xsl:sort select="(@Name | @Sortname[not(../@Name)])[1]"/> can be 
further simplified to
   <xsl:sort select="(@Name | @Sortname[not(../@Name)])"/>
The '|' is the union operator so what you do is taking the union of the 
'Name' attribute and the 'Sortname' attribute not having a parent with a 
'Name' attribute.
That way you ensure that, if the 'Name' attribute is present, you sort 
on the 'Name' attribute, and if 'Name' is not present, then you sort on 
the 'Sortname' attribute.
