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.

Yes but my original question was what was the type of

<xsl:variable name="thing">"<xsl:value-of
select="replace(.,',',concat($quot,',',$quot))"/>"</xsl:variable> and
the value of the variable $quot is obvious.

precisely because xs:string+ (although it types checks) wasn't giving
the right result and omitting a type does.
