Visual Studio Shell for SQL Server 2012 Integration Services

Not sure where EXACTLY this post belongs because I'm not sure about the cause of the error - Visual Studio, or SSIS or underlying framework or an XML document. I'm starting here because I believe VS shell might be the culprit.

I'm trying to add a web service task via [[Visual Studio 2010 Shell for SQL Server 2012 SSIS]].

I have the wsdl file and the xsd file in the same folder. When I try to reference the wsdl file below, I get the error from Visual Studio:

The root element of a W3C XML Schema should be

<schema>

Also - the same xml/xsd produce perfect .cs proxy code when used with the wsdl.exe tool. And the service gives expected results when called via that code. It's just the Visual Studio 2010 shell for SSIS that is giving the above error.

Here are the first few lines of the 13,000 line wsdl file:

<?xml version="1.0" encoding="UTF-8"?><definitions xmlns="http://schemas.xmlsoap.org/wsdl/" xmlns:http="http://schemas.xmlsoap.org/wsdl/http/" xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/" xmlns:s="http://www.w3.org/2001/XMLSchema" xmlns:s0="http://www.cisco.com/AXLAPIService/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:tm="http://microsoft.com/wsdl/mime/textMatching/" xmlns:xsd1="http://www.cisco.com/AXL/API/8.0" targetNamespace="http://www.cisco.com/AXLAPIService/"><import location="AXLSoap.xsd" namespace="http://www.cisco.com/AXL/API/8.0"/><message name="addSipProfileIn"><part element="xsd1:addSipProfile" name="axlParams"/></message></import>

First few lines of AXLSoap.xsd:
