isOptional doesn't work about jsdoc-toolkit HOT 3 CLOSED

I can't reproduce this in version 1.3.0. I get the expected...

<params>
  <param>
    <type>integer</type>
    <name>employeeId</name>
    <desc>The id of the employee.</desc>
    <optional>false</optional>
  </param>
  <param>
    <type>string</type>
    <name>newRole</name>
    <desc>The new role of the employee.</desc>
    <optional>true</optional>
  </param>
</params>

Can you send me more information (email me directly if necessary): the source 
file,
the exact output, the exact commandline you are using?

I'm sorry, just found my bug in the template file ...
