    OCL: self.isDTDpresent()
    Description: The example rule checks if a DTD is given.

     

    The XML snippet below would pass this check.

    <?xml version="1.0" encoding="UTF-8"?>

    <!DOCTYPE people_list SYSTEM "example.dtd">

    <Message xmlns="http://www.XMLdation.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instancexsi:schemaLocation="http::xmldation.com extensions.xsd ">

      <Transaction>

        <Creditor>
          <Name>Creditor1</Name>
        </Creditor>
      </Transaction>
    </Message>

    The other snippet below however would not pass this check.

    <?xml version="1.0" encoding="UTF-8"?>
