Avoiding D-O-E (Continued)

Construct a character map that turns those characters back into the invalid strings:

<xsl:character-map name="jsp">
  <xsl:output-character char="«"
                        string="&lt;%"/>   
  <xsl:output-character char="»"
                        string="%&gt;"/>
  <xsl:output-character char="·"
                        string='"'/>
</xsl:character-map>
