<!--

This sun-cmp-mapping_1_2.dtd has a workaround for an unfiled schema2beans bug
which prevents us from having the DTD specify the sub-elements in column-pair as
it really should be.  This issue is fixed in schema2beans shipped with NB > 3.5,
but we are currently using schema2beans from NB 3.5, and so must use this
workaround.

Because of the workaround, the file here differs from the official one in
appserv-commons/lib/dtds (which also has previous versions of sun-cmp-mapping 
dtds) in the definition of the column pair element.  This difference is so 
that schema2beans can produce usable beans.  The official dtd has:

    <!ELEMENT column-pair (column-name, column-name) >

and the one in here has:

    <!ELEMENT column-pair (column-name+) >

     is used as the SOURCE for getting the value from the database.  The 
     columns are updated in their order.  A field may also be marked as 
     read-only.  It may also participate in a hierarchial or independent
