[xsl] curly braces in attributes

[Mansour Al Akeel <mansour.alakeel@xxxxxxxxx>]

I am trying to generate xml that contains attributes with with curly braces.
My style sheet has something like:

        <target name="clean" >
             <delete dir="${basedir}/target" />
        </target>

The results I am getting now is:

    <target name="clean" >
        <delete dir="$/target"/>
    </target>

I am expecting the same to output the same text. I tried to use
<xsl:text> and CDATA. The only way I was able to get the output I
needed is using CDATA inside <xsl:text> for the parts,
I need to output unchanged and unescaped.

Is there a better to disable expression evaluation. Thank you.
