XSL if else condition

We can achieve if else by using below code

<xsl:choose>
    <xsl:when test="something to test">

    </xsl:when>
    <xsl:otherwise>

    </xsl:otherwise>
</xsl:choose>

So here is what I did

<h3>System</h3>
    <xsl:choose>
        <xsl:when test="autoIncludeSystem/autoincludesystem_info/@mdate"> <!-- if attribute exists-->
            <p>
                <dd><table border="1">
                    <tbody>
                        <tr>
                            <th>File Name</th>
                            <th>File Size</th>
                            <th>Date</th>
                            <th>Time</th>
                            <th>AM/PM</th>
                        </tr>
                        <xsl:for-each select="autoIncludeSystem/autoincludesystem_info">
                            <tr>
                                <td valign="top" ><xsl:value-of select="@filename"/></td>
                                <td valign="top" ><xsl:value-of select="@filesize"/></td>
                                <td valign="top" ><xsl:value-of select="@mdate"/></td>
                                <td valign="top" ><xsl:value-of select="@mtime"/></td>
                                <td valign="top" ><xsl:value-of select="@ampm"/></td>
                            </tr>
                        </xsl:for-each>
                    </tbody>
                </table>
                </dd>
            </p>
        </xsl:when>
        <xsl:otherwise> <!-- if attribute does not exists -->
            <dd><pre>
                <xsl:value-of select="autoIncludeSystem"/><br/>
            </pre></dd> <br/>
        </xsl:otherwise>
    </xsl:choose>

My Output
