Cannot find the declaration of element 'wsdl:definitions'

I have tried to search a solution to my problem and didn't succeed.

When I am trying to validate my XML file with the XSD I am getting the next error:

"cvc-elt.1: Cannot find the declaration of element 'wsdl:definitions'"

I am validating it with http://www.xmlvalidation.com/index.php?

in other validator I am getting:

element definitions: Schemas validity error : Element '{http://schemas.xmlsoap.org/wsdl/}definitions': No matching global declaration available for the validation root.

My XML/wsdl file is

 <?xml version='1.0' encoding='UTF-8'?><wsdl:definitions xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:tns="http://com.my.company/IFBTCIBPSI" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" name="IFBTCIBPSI" targetNamespace="http://com.my.company/IFBTCIBPSI">
