How to disable validation.

 I have a question about DTD's.

 Here is the (simplified) situation.

 Let's consider that we have company A 
 processing XML documents of some 
 kind ( A-documents), validating those 
 documents with some DTD ( let's call 
 it A.DTD ).

 Company B does the same validation-based 
 processing with their B-documents.

 The only difference between A-documents and  
 B-documents is that A-documents have
 <A1> element that is specific to company A
 and B-documents have <B1> element specific
 to company B - the rest of elements and 
 attributes are the same for both companies.
 Now our companies decided to exchange 
 their documents. As a solution they may write 
 XSL stylesheets, or ( maybe) use entities 
 to remove A1 elemets and B1 elements. 
 I see no other ways to workaround this 
 situation and both are a bit complicated.

 The problem here is to hide some part of 
 XML document from the validation process.

 If company B could say in B.DTD something 


 And company A would add to A.DTD


 That will allow both companies to do 
 whatever they like inside their elements
 ( A1 and B1 would become attributes, for example )
 and easily exchange the documents without 
 any ( even simple ) XSL-based ( or not XSL-based ) 

 I'm sure there is some answer to this  
 "how to hide some part of  XML document 
 from validation?" 

 I'l appreciate if you'l provide me with any 
 URL that may be related to this problem.

 Thank you.
