<xsl:variable name="val">"<xsl:sequence
select="replace(.,',',
...
If you type $val as xs:string+ you don't get the right result, if you
type it as xs:string it doesn't type check.
Thats because you have a text node (the ") then the xsl:sequence... so
you will always get a sequence of more than 1 item.
If you want to use xs:string, you need to make sure the contents of
the variable is sequence of 1 item.
