Could not initialize variable. An error occurs while initializing BPEL .

Question

I have the following error:
**Could not initialize variable. An error occurs while initializing BPEL variable inputVariable; the schema processor cannot find the element {http://xmlns.oracle.com/MRTApplicationWorkflow/Project1/BPELProcess1}processRequest in the following schemas: oracle.fabric.common.wsdl.SchemaManager@e92e05. The XSD element on which the variable was based was not properly defined in XSD or the WSDL. Ensure that the element named in the error message is valid in the XSD or the WSDL.**
My process input xsd below:

Answer 1

Please check your XSD and dependant XSD's whether it contains any special characters.
I solved the same issue in my BPEL process by commenting the special characters included in <documentation> element of XSD.
