SGML Parsing error - ATA iSpec 2200

[COTRONEO Tracey]

Hi
 
I'm working with several ATA iSpec 2200 DTDs and trying to save my .fm
files to SGML and receiving the following error:
 
   "End tag (para) implied by the start tag (revst); not declared
minimizable"
 
This is my sgml output:
 
    <subtask chapnbr = "25" sectnbr = "24" subjnbr = "01" func = "000"
seq = "000" pgblknbr = "4" chg = "N" key = "C25_S24_S01_P04_ID9" revdate
= "20070831">
    <effect effrg = "001,  051-052,  101-106,  206-208,
211-221"></effect>
    <list1>
    <l1item>
    <para>Installations of the APU Generator
    </para>
    <list2>
    <l2item>
    <para>Replace the .....
    </para>
    </l2item>
    <l2item>
    <para>Make sure the .......
    </para>
    </l2item>
    <l2item>
    <para>

    </para>
    </l2item>
    </list2>
    </l1item>
    </list1>
    </subtask>

The <revst> and <revend> elements are inclusions in the DTD and are
defined as:
 
    <!ELEMENT revst     - O EMPTY                                      >
    <!ELEMENT revend    - O EMPTY                                    >
 
 
Please HELP ME!
