Description

>> Note #1: I was unable to find a forum and this was the only means of communication I found for this project.
>> Note #2: Searched the DB before creating this issue to skip duplicates.

>> Description: Unable to serialize object. (most likely why it's failing to deserialize as well).

>> In generated code:
...
xsi_type_attri = axiom_attribute_create (env, "type", "LocomotiveInformationTransaction", xsi_ns);
//The following line results in ERROR:
axiom_element_add_attribute (parent_element, env, xsi_type_attri, parent);
...

>> The error. (from wlis.log):
...
[error] om_element.c(283) Wrong element type or null node
...

>> Pasting part of the wsdl file (i couldn't attach it, let me know if you need the entire file):

The only thing I could see that stood out was the namespace it was using. In this case, it looked like (after stepping through the code and lots of debugging log statements) it was using the default "xsi" namespace. Tried hard coding "ns1" as the namespace for LocomotiveInformationTransaction but that did not resolve the issue.
