Are whitespace text nodes tripped out in varaibles?

  Hi

  Is the expected behaviour that the whitespace text nodes are stripped
out in a document node constructed in a variable?  If it is, does
someone can point me out relevant parts of the recommendation? 
Following is a simple test tested with Saxon 8.6.1:

    ~/drafts/fctx $ cat white-spaces.xsl 
    <xsl:stylesheet
        xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
        version="2.0">

      <xsl:output method="text"/>

      <xsl:preserve-space elements="elem"/>

      <xsl:variable name="var">
        <elem>
          <a/> <b/> bla <c/>
        </elem>
      </xsl:variable>

      <xsl:template match="/">
        <xsl:apply-templates select="$var/elem/(*|text())"/>
      </xsl:template>

      <xsl:template match="*">
        <xsl:text>Elem #</xsl:text>
        <xsl:value-of select="position()"/>
        <xsl:text>: </xsl:text>
        <xsl:value-of select="local-name()"/>
        <xsl:text>&#10;</xsl:text>
      </xsl:template>

      <xsl:template match="text()">
        <xsl:text>text #</xsl:text>
        <xsl:value-of select="position()"/>
        <xsl:text>: [</xsl:text>
        <xsl:value-of select="."/>
        <xsl:text>]&#10;</xsl:text>
      </xsl:template>

    </xsl:stylesheet>
    ~/drafts/fctx $ saxon white-spaces.xsl white-spaces.xsl
    Elem #1: a
    Elem #2: b
    text #3: [ bla ]
    Elem #4: c
    ~/drafts/fctx $
