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:
