I think the answer is nr 2, but I am not sure. I also think that XML is case sensetive, could somone help?

  1. An XML schema in the Document Type Definition (DTD) format can be described more expressively than a in the XML Schema Definition (XSD) format.

  2. An XML document must have one or more root elements.

  3. A well-formatted XML document must follow a specified XML schema.

  4. XML is case sensitive.

This is a question from w3schools. Hope somone can help.

  1. False, XSD can describe any constraint that can be expressed in a DTD, but the reverse is not true.

  2. A document must have exactly one root element. Call that true or false depending on how you read the question.

  3. False.

  4. True.
