I'm using XSLT2.

I need to construct a complex string in a variable. I wanted to use XSLT
instructions for this, not pure XPath. I'm struggling with coercing the result
of the <xsl:variable> body to a single xs:string, not a sequence of

<xsl:variable name="var" as="xs:string">
  <xsl:value-of select="'part1'"/>
  <!-- follows more complex code producing further fragments of desired result
string -->

This gives me the error message (Saxon HE 9): "A sequence of more than one
item is not allowed as the value of variable $var ("prefix", "part1")"

Of course, I could declare the variable as xs:string+ and then use
string-join( $var, '' ) on every use of $var, or create another variable that
holds the concatenated result of $var.

Is there a better way to do this?
