Re: Constructing complex xs:string in variable

Re:  Constructing complex xs:string in variable
And to explain why David's version works: value-of and xsl:text both result in
text nodes, not strings. So a sequence of xsl:value-of and xsl:text
instructions will result in a sequence of text nodes when are then converted
to strings resulting in a sequence of strings.

Wrapping everything in a single xsl:value-of results in a single text node and
thus a single string.

Looking at this now I realize it never occurred to me that xsl:value-of can
have content and not just a @select attribute. Learn something new every day.

Cheers,

E.

    <xsl:variable name="var" as="xs:string">
    <xsl:value-of>
      <xsl:text>prefix</xsl:text>
      <xsl:value-of select="'part1'"/>
