    Two problems:

    1. There needs to be a space after <!ELEMENT COUNTRY before the left parenthesis (applies to all the other <!ELEMENT... tags as well.
    2. The <COUNTRYINFO> element needs to be declared

    Corrected DTD:

    <!DOCTYPE COUNTRYINFO
[
<!ELEMENT COUNTRYINFO (COUNTRY)>
<!ELEMENT COUNTRY (NAME, POPULATION, AREA)>
<!ELEMENT NAME (#PCDATA)>
<!ELEMENT POPULATION (#PCDATA)>
<!ELEMENT AREA (#PCDATA)>
]>
