RE: [xsl] Cannot use result tree fragment

---

---

When people write

<xsl:variable name="x">
  <xsl:value-of select="ABCD"/>
</xsl:variable>

they nearly always should be writing

<xsl:variable name="x" select="ABCD"/>

Sometimes the only effect of doing it the first way is that it runs
slower. Sometimes the effect is that it doesn't work at all.

You have copied the string value of the document into a text node. The
elements have disappeared, so even if XSLT 1.0 didn't have restrictions
on using result tree fragments, your path expression would find nothing.
