BizTalk Xml Links ...

• Import, Include or Redefine
  
  

  
  Even though you could use <xs:import> or <xs:include> to reuse existing schemas, I found that BizTalk having some proprietary processing for <xs:include>. It will copy the included schema verbatim whenever you place your <xs:include> node. Moreover, the schemas will also be included whenever they are referenced. Thus, you will have multi-rooted master schema if you use <xs:include>. I prefer to use the <xs:import> because it will maintain the single root in the master schema even you reference multiple existing external schemas.
