How to insert an HTML entity with an XSL stylesheet into a DOM result and then serialize it in HTML ?

Dear colleagues,

I'm trying to 
- take an XML document: xmlSource
- applying an XSL stylesheet to it:
transformer.transform (new DOMSource(xmlSource),new DOMResult(myDOMTree));
- appending the result to an existing XMLC HTML object myContentHTML.java
 myContent.getElementMydoc.appendChild(myContent.importNode(myDOMTree, true));
- and displaying the result through a presentation object
        OutputOptions.setDropHtmlSpanIds(true);

OutputOptions.setXmlEncoding("UTF-8");
DOMFormatter fFormatter = new DOMFormatter(OutputOptions);
buffer = fFormatter.toBytes(myContent.getLayout());
comms.response.setContentLength(buffer.length);
out = comms.response.getOutputStream();
out.write(buffer);

Everything works fine except when I want to add html entities in my XSL stylesheet:

<xsl:stylesheet version="1.0" ... >

<xsl:output method="html" encoding="utf-8" indent="yes"/">

<xsl:template match="/">
<xsl:text>&lceil;</xsl:text>
<xsl:apply-templates/>
</xsl:template> 
</xsl:stylessheet> 

I tried several methods:

The first one: <xsl:text>&lceil;</xsl:text>
I cannot even parse my xsl stylesheet because 
Reason: class main.business.PapillonBusinessException: Exception in parseXslSheet(): The entity "lceil" was referenced, but not declared. 

The second one: <xsl:text>&amp;lceil;</xsl:text>
Works but displays the entire entity "&lceil;" instead of its content "⌈" !

The third one: <xsl:text disable-output-escaping="yes">
Does not work !

Reason: class org.enhydra.xml.io.XMLIOError: Unexpected call to handleProcessingInstruction 
Java Call Stack:
org.enhydra.xml.io.XMLIOError: Unexpected call to handleProcessingInstruction
at org.enhydra.xml.io.HTMLFormatter.handleProcessingInstruction(HTMLFormatter.java:274)
at org.enhydra.xml.dom.DOMTraversal.processNode(DOMTraversal.java:369)

The fourth one: <![CDATA[  &lceil; ]]>
Is like the second one: works but displays the entire entity "&lceil;" instead of its content "⌈" !

The fifth one: <xsl:text><![CDATA[  &lceil; ]]></xsl:text>
Is like the second one: works but displays the entire entity "&lceil;" instead of its content "⌈" !

The last one: I also tried to write directly the character in UTF-8 "⌈" instead of an entity 
but the result is displayed with the ISO-8859-1 characters representing the entity: åà.
(when I have UTF-8 characters in the XML document, I have no problem)


Anyone has an idea ?

Thank you for your help !
