I've repro'd and confirmed the bug you report.  It should be fixed in an
upcoming maintenance release.  Until then, you can work around this bug
by adding an empty <xsl:text/> instruction just before the
<xsl:number/>:

  <xsl:variable name="num">
    No.<xsl:text/><xsl:number/>
  </xsl:variable>

Thanks for reporting this bug.
