SOAP::Lite client - deserializer.
The soapenc:arrayType attributes describes the manner by which an array of elements should be encoded within the SOAP request, the default value supplied in your code being that specified within the xsd namespace (http://www.w3.org/1999/XMLSchema). In order to specify the alternate array encoding however, you are likely to have to build the SOAP data structure at a lower level using SOAP::Data::Builder.
perl -le "print unpack'N', pack'B32', '00000000000000000000001011101010'"
