XML to DTD error: the document type declaration must be well-formed

I'm a beginner to XML, I have to convert the following XML to DTD 

<student id="12C042">

    <fName>John</fName>

    <lName>Nelson</lName>

    <plan>

        <courses year="3">

            <course>

                <name> Extensible Markup Language</name>

                <shortName>XML</shortName>

                <record>

                    <grade>30</grade>

                    <date>12-Jan-2017</date>

                </record>

            </course>

            <course>

                <name>Object Oriented Concepts and Unified Modeling Language</name>

                <shortName><![CDATA[OOP & UML]]></shortName>

            </course>

        </courses>

    </plan>

This is the DTD, I obtained after conversion:

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

<!ELEMENT student (fName,lName,plan)>
<!ATTLIST student
  xmlns CDATA #FIXED ''
  id NMTOKEN #REQUIRED>

<!ELEMENT fName (#PCDATA)>
<!ATTLIST fName
  xmlns CDATA #FIXED ''>

<!ELEMENT lName (#PCDATA)>
<!ATTLIST lName
  xmlns CDATA #FIXED ''>

<!ELEMENT plan (courses)>
<!ATTLIST plan
  xmlns CDATA #FIXED ''>

<!ELEMENT courses (course)+>
<!ATTLIST courses
  xmlns CDATA #FIXED ''
  year CDATA #REQUIRED>

<!ELEMENT course (name,shortName,record?)>
<!ATTLIST course
  xmlns CDATA #FIXED ''>

<!ELEMENT name (#PCDATA)>
<!ATTLIST name
  xmlns CDATA #FIXED ''>

<!ELEMENT shortName (#PCDATA)>
<!ATTLIST shortName
  xmlns CDATA #FIXED ''>

<!ELEMENT record (grade,date)>
<!ATTLIST record
  xmlns CDATA #FIXED ''>

<!ELEMENT grade (#PCDATA)>
<!ATTLIST grade
  xmlns CDATA #FIXED ''>

<!ELEMENT date (#PCDATA)>
<!ATTLIST date
  xmlns CDATA #FIXED ''>

The compiler gives following error:

Fatal error:
Public ID: null
System ID: file:/home/p12947/studentdtd.dtd
Line number: 9
Column number: 2
Message: The markup declarations contained or pointed to by the document type declaration must be well-formed.

try to enclose your elements by a 'student' element

a valid document according to your dtd could look like this

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE student SYSTEM "student.dtd">
<student id="1">
<fName>John</fName>
<lName>Nelson</lName>
<plan>
    <courses year="3">
        <course>
            <name> Extensible Markup Language</name>
            <shortName>XML</shortName>
            <record>
                <grade>30</grade>
                <date>12-Jan-2017</date>
            </record>
        </course>
        <course>
            <name>Object Oriented Concepts and Unified Modeling Language</name>
            <shortName><![CDATA[OOP & UML]]></shortName>
        </course>
    </courses>
</plan>
</student>
