Where does Word Document Store the attached XML Schema?

[AmjaD]

In my application, there's an edit box where the user enters full path to a
Word document (.doc). On the "Get Schema" button, I need to parse the word
document and extract the schema it references and show the XML Schema (XSD)
in a tree.

Does anyone know, Where does the word document store the XML Schema?
Does it store the xml schema inside it (active document)?
OR
Does it store the xml schema in the Schema Library?

In any case, how can I get the referenced schema(s) from there
programmatically?

ANy ideas?
