[Xml-compile] setting nil attribute with wsdl derived clients

[Mark Blackman]

Hi,

I need to submit an explicit NIL for a SOAP parameter, however I'm  
merely using
the WSDL derived client (via compileClient) and so I'm not sure how to  
encode
an  xsi:nil="true" attribute in the %request hash. any suggestions?

This is the definition of the parameter in the WSDL

<s:element minOccurs="1" maxOccurs="1" name="DateOfBirthFilter"  
nillable="true" type="s:dateTime" />
