Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
XML Schema (XSD) is used to define the structure and constraints of XML documents.
It provides strong support for data typing.
Step 1: Understand XML Schema.
XML Schema supports various data types such as:
• String
• Integer
• Boolean
• Date
• Time
• Decimal
Step 2: Compare with DTD.
DTD mainly defines structure. DTD has very limited support for data types. XML Schema provides extensive datatype support.
Step 3: Select the answer.
Hence, \[ \boxed{\text{XML Schema}} \] is correct.
