Howto use BizTalk TestableReceivePipeline when having a schema which has an imported schema - testing

Question

Under Microsoft BizTalk 2009, we want to test the ReceivePipeline(which has a Flat file disassembler) with the built-in TestableReceivePipeline class.
It works fine if we use one single Schema, but it throws an error (System.Xml.Schema.XmlSchemaException: The 'ABC' element is not declared.) when we try to use a schema(Schema1) which has an imported schema(Schema2) inside.
Why I'm getting this error?
code for testing pipeline:
StringCollection documents = new StringCollection();
documents.Add(#"c:\Test.dat");
StringCollection parts = new StringCollection();
Dictionary<string, string> schemas = new Dictionary<string, string>();
schemas.Add("MyCompany.Schema2", #"C:\Schema2.xsd");
schemas.Add("MyCompany.Schema1", #"C:\Schema1.xsd");
Microsoft.BizTalk.TestTools.Pipeline.TestableReceivePipeline pipeline = new MyReceivePipeline();
pipeline.TestPipeline(documents, parts, schemas);
Schema1.xsd source:
<xs:import schemaLocation=".\Schema2.xsd" namespace="http://MyCompany.Schema2" />

AFAIK this is currently not supported in BizTalk 2009.
