Which of the following statements is not true about XML Schemas:

  • A.They are used to define the content and structure of data.
  • B.They define a set of symbols and the relationships of those symbols.
  • C.
    They are themselves XML documents.
  • D.They have their own syntax.

Answer: D

Correct answer: They have their own syntax.

An XML Schema is itself an XML document, so it uses XML syntax and nothing else - which is precisely what distinguishes it from a DTD, which does have a syntax of its own. The consequence is convenient: a schema can be parsed, validated and manipulated by ordinary XML tools.
