Empty parameters with the tag

I discovered a problem with the <s:param /> tag when attempting to pass an
empty parameter.

<s:url var="myUrl" action='MyAction'>
     <s:param name="p1" value=""/>
     <s:param name="p2"></s:param>
</s:url>

I was attempting to pass an empty parameter using the "p1" syntax above and
the parameter was being suppressed.

Using the "p2" syntax it works correctly, and the empty parameter is
included.

The doc http://struts.apache.org/docs/param.html says that
"suppressEmptyParameters" defaults to false but the p1 parameter was always
suppressed even if I added suppressEmptyParameters="false".

Also the doc http://struts.apache.org/docs/param.html has an incorrect
example on how to use the suppressEmptyParameters option.

<s:param name="suppressEmptyParameters" value="true"/>
