Hello,
I have created a Custom Object schema using two XSD files, transport_order.xsd and transport_schema.xsd. One file (transport_order.xsd) is the main schema file, while the other (transporeon_schema) is a general schema file that contains definitions for all the transactions of a third party. The main schema references the node 'transport_order' from the transporeon_schema.xsd file. I can successfully created the object schema in ION, but I am having difficulty utilizing it in the IEC mapper input schema.

Mapper Name:
M3BOD_TransporeonTransportOrder_Load_In_1_0_0_Custom
Noun Name : transport_order
Below is how the files are created in the mapping folder.

When I try to import the input schema, I am encountering the below error

transport_order.xsd prolog:

transporeon_schema.xsd - prolog:

basically I copied the files from the Object schema I created in ION Desk. Could some one help me understand why I am receiving this validation error? I could not find any issues with the prolog, but still unable to import the schema into the mapper. Is it possible that the XSD file is not accepted by the Mapper plugin, or could there be another issue?
Any suggestions would be appreciated.
Thank you!
