Problem with jsp expression %>"

Hi
I have a problem related with a XSL that i have like this:
What i want to generate is this simple code for example.
..
followUp="<%=var%>"
..
and it always get like this
followUp="<%=var%>'


My XSL code is this... 

<xsl:text disable-output-escaping="yes">followUp="&lt;%=var%&gt;"/></xsl:text>

What is wrong? does anyone knows? If i put a space or a tab or something after 
my %&gt; it generate the " .. but i cannot do that in my code.
Can anyone tell me what is this problem?

Many thanks
