Document Structure Description
Document Structure Description, or DSD, is a schema language for XML, that is, a language for describing valid XML documents. It's an alternative to DTD or the W3C XML Schema. An example of DSD in its simplest form: This says that element named "foo" in the XML namespace " http://example.com " may have two attributes, named "first" and "second". A "foo" element may not have any character data. It must contain one subelement, named "bar", also in the " http://example.com " namespace. A "bar" element is not allowed any attributes, character data or subelements. One XML document that would be valid according to the above DSD would be:
