title: How to compare 2 xsd schema files for equivalent functionality
body: <p>I would like to compare 2 XSD schemas A and B to determine that all instance documents valid to schema A would also be valid to schema B. I hope to use this to prove that even though schema A and B are "different" they are effectively the same. Examples of differences this would not trigger would be Schema A uses types and Schema B declares all of it's elements inline. </p>
  
  <p>I have found lots of people talking about "smart" diff type tools but these would claim the two files are different because they have different text but the resulting structure is the same. I found some references to XSOM but I'm not sure if that will help or not.</p>
  
  <p>Any thoughts on how to proceed?</p>
