1. Write an appropriate DTD tag that would validate an earthquake element given these requirements: nested elements 
   must appear in order with exactly one date, one location, one magnitude, and one or more recording_sensor elements 
   per earthquake.
      <!ELEMENT earthquake (date, location, magnitude, recording_sensor+)>
   Write the appropriate DTD tag(s) that would validate a date elementís attributes given these requirements: 
   All date elements must have year, month, day, hour, minute, and millisecond attributes. There is no 
   requirement as to which order the attributes must appear.
      <!ELEMENT date EMPTY>
      <!ATTLIST date year CDATA #REQUIRED>
      <!ATTLIST date month CDATA #REQUIRED>
      <!ATTLIST date day CDATA #REQUIRED>
      <!ATTLIST date hour CDATA #REQUIRED>
      <!ATTLIST date minute CDATA #REQUIRED>
      <!ATTLIST date millisecond CDATA #REQUIRED>
      Note: The !ELEMENT DTD element was not required in the answer. I add that for context here.
2. Fill in the rest of the XML encoding here to create a valid earthquake element according to the requirements
   and DTDs you generated in question 1 (make up valid element and attribute values of your choice):

            <depth units="meters">2209.8</depth>

    wasn't caused by your contribution (circle YES or NO)?
