Escape Special Characters

I'm baffled by this use of &. I have to use it
twice for each & sign in the URL to get the variables
passed correctly. Does someone have explanation for
this?


<xsl:element name='img'>
        <xsl:attribute name='src'>
                <xsl:text>./php/chart_age.php?     age1=</xsl:text>
                <xsl:value-of select="AGE1"/>&amp;
                <xsl:text>&amp;age2=</xsl:text>
                <xsl:value-of select="AGE2"/>&amp;
                <xsl:text>&amp;age3=</xsl:text>
                <xsl:value-of select="AGE3"/>&amp;
                <xsl:text>&amp;age4=</xsl:text>
                <xsl:value-of select="AGE4"/>&amp;
                <xsl:text>&amp;age5=</xsl:text>
                <xsl:value-of select="AGE5"/>&amp;
                <xsl:text>&amp;age6=</xsl:text>
                <xsl:value-of select="AGE6"/>&amp;
                <xsl:text>&amp;age7=</xsl:text>
                <xsl:value-of select="AGE7"/>&amp;
                <xsl:text>&amp;age8=</xsl:text>
                <xsl:value-of select="AGE8"/>
        </xsl:attribute>
</xsl:element>

Thanks.
