I was tired of writing a large complex data with plain SOAP::Data and was so glad to have found SOAP::Data::ComplexType

Stop right there. You don't have to construct SOAP::Data hierarchies by hand!. Use SOAP::WSDL (instead of SOAP::Lite), which

• handles the namespaces for you
• constructs outgoing complexType values (including arrays) automatically from normal perl data-structures.
• is a subclass of SOAP::Lite.

I simply cannot believe how many folks are doing this the hard way. It's almost like Perl-based users of SOAP hate themselves ;)

A service method Foo expecting an array of xsd:string elements for the argument called 'Words' can be called as follows:

  $soap->Foo(Words => [qw/this is a test!/]);

No need to hand-construct anything under SOAP::Data at all.
