You work in an international company which is named TXTWIN. And you’re in charge of the company network and use Microsoft BizTalk Server 2006 R2.
You business partner send messages to you and each of them has their own custom message format to use. In order to use a standard message format to process all messages, an XML schema is created for each custom message format. The schema displays the standard message format. So what’s your next action?

A.
For each custom message format, you should create a map.
The custom XML schema should be specified as the source schema, and the standard XML schema should be specified as the destination schema.

B.
For each custom message format, you should create a map.
The custom XML schema should be specified as the destination schema, and the standard XML schema should be specified as the source schema.

C.
In the Document Schemas property of the XML Disassembler Properties tab, specify the custom XML schema.
Before you do this, a custom receive pipeline should be created and an XML Disassembler pipeline component should be added from the toolbox.

D.
In the Document Schemas property of the XML Disassembler Properties tab, the standard XML schema should be specified.
Before you do this, a custom receive pipeline should be created and an XML Disassembler pipeline component should be added from the toolbox.
