Benefits of XML schema over DTD
Write the benefits of XML schema over the DTD.
Expert
Microsoft developed the language termed as XML Schema Definition (XSD) which describes the schema to the XML document. The benefits of XML schemas over DTDs are as follows:
• XSD is quite simple to learn and to understand as its syntax is similar to that of XML document.
• DTD does not permit to create customized data types whereas XSD offers full support to create modified data types.
• XSD permits us to state restrictions on the data. This means that we can describe the type of data which must be stored in the element, like numbers or alphabets.
• XSD keeps much better control over types of data than the DTD.
