Disable-output-escaping Question

I hear that this is the place to ask about disable-output-escaping in XSL.
If I am correct, I would like to ask a minute of your time to help me with a
problem I'm trying to solve.

I'm currently porting our product and I am forced to use a new
implementation of XML parsing/transforming.  In this implementation, they
have documented that the new parser does *not* support the
disable-output-escaping attribute.  I use this tag quite often; to create
non-breaking spaces, to start HTML tags without finishing them so the parser
doesn't blow up, etc.  Is there a different and/or better way to do this?
An example of what I'm doing now is this; every page includes a global.xsl
that has a HEADERBUILD template in it - this template does alot, but
essentially it starts the <html> tag, while the FOOTERBUILD template is
responsible for ending that tag.  So, from a bird's-eye level, the code
looks a little like this:

	<xsl:template name="HEADERBUILD>
		<xsl:text disable-output-escaping="yes">
			&lt;html&gt;
		</xsl:text>
	</xsl:template>

	<xsl:template name="FOOTERBUILD">
		<xsl:text disable-output-escaping="yes">
			&lt;/html&gt;
		</xsl:text>		
	</xsl:template>

This used to build the <html> tag with it's respective closing </html> tag
just fine with the old parser.  Now it just transforms into "&lt;html&gt;"
and "&lt;/html&gt;" as the output.  If you know of a way to accomplish this
without disable-output-escaping, please enlighten me!  I've been searching
all over the internet for an answer but cannot find one..

Thanks!

Sorry, but your "way of thinking" is completely wrong. You must change your 
code, you don't need such things like &lt;htmlgt; !!!

For example:

XML:

<page>
   <title>Test</title>
   <text>test test test test</text>
   <text>test2 test2 test2 test2</text>
   <image src="image.jpg"/>
</page>

XSL:

<xsl:stylesheet ....>
<xsl:output method="html"/>

<xsl:template match="page">
   <html>
     <head><title><xsl:value-of select="title/></title></head>
     <body>
       <xsl:apply-templates/>
     </body>
   </html>
</xsl:template>

<xsl:template match="text">
   <p><xsl:value-of select="."/></p>
</xsl:template>

<xsl:template match="image">
   <img src="{@src}"/>
</xsl:template>

</xsl:stylesheet>

For building your HTML in your way, you don't need XSL, there would be 
easier ways. But with using XSL in the "correct" way, you get a powerful 
technology! I hope I could set you thinking about it. If you want more help 
or information about XSL, ask a XSL-list like

http://www.mulberrytech.com/xsl/xsl-list/

or

http://groups.yahoo.com/group/XSLTalk

or read such a tutorial like Norman Walsh's

http://www.nwalsh.com/docs/tutorials/xsl/xsl/slides.html

Hope this helps,

Joerg
