Sure.  An xsl:variable can be assigned the result of a 'select' or can
be used as a container for template instantiation.  In the latter case,
you can roam around, generating any kind of output you want, and instead
of going directly into the result tree ("output") it goes into the
variable, which is then of type Result Tree Fragment (RTF).  An RTF can
be used like a string, which is adequate for your purposes.

So, you can just do the following:

test.xml:
<test>
  <elem>This</elem>
  <elem>is</elem>
  <elem>a</elem>
  <elem>test</elem>
</test>

concat.xsl:
<xsl:stylesheet version="1.0" 
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:variable name="elements">
  <xsl:text>Value of $elements: </xsl:text>
  <xsl:for-each select="/test/elem">
    <xsl:value-of select="."/>
    <xsl:if test="position() &lt; last()">
      <xsl:text> </xsl:text>
    </xsl:if>
  </xsl:for-each>
  <xsl:text>.</xsl:text>
</xsl:variable>

<xsl:template match="/">
  <xsl:value-of select="$elements"/>
</xsl:template>

</xsl:stylesheet>

Note that the elements don't have to have the same name here; you could
use the results of any 'select' that is legal within xsl:for-each.
