RE: Here's why it's not always a good idea to embedvalidation
Hello John, > Was there ever a good reason to embed validation information > in an instance document? In education settings, where you are learning XML Schemas and doing validations one at a time using an IDE, it is convenient to embed schemaLocation within instance documents. And, in a closed environment where you are certain of who's sending the data, it may be convenient to embed schemaLocation within the instance document. > Isn't that [embedding schemaLocation within instances] fundamentally backwards, > like trusting a thief because /he says/ he's not a thief?

Subject: Re: Here's why it's not always a good idea to embed validation information (e.g., schemaLocation) in instance documents Hi Roger, Your presentation looks good, but I'm not sure it goes far enough. Was there ever a good reason to embed validation information in an instance document? Isn't that fundamentally backwards, like trusting a thief because /he says/ he's not a thief?
