Advantages of XSD over DTD
- XSD is extensible. You can derive new elements from the existing elements.
- XSD is defined in XML. It does not require intermediate processing by a parser.
- XSD supports data types.
- XSD supports default values.
- XSD supports references to external XML schemas.

It is easier to validate the correctness of data. It is easier to define data facets (restrictions on data) It is easier to define data patterns (data formats)
How to create an XML Schema using XML parser?
