/**
 * The maintainableField element defines the specifications for one data field.
 * JSTL: maintainableField is a Map accessed by the field name.
 * It contains entries with the following keys:
 *      * field (boolean String)
 *      * name (String)
 *      * required (boolean String)
 *
 * name is the name of the field
 * required is true if the field must contain a non-null value
 * readOnly is true if it cannot be updated
 * template documentation from MaintenanceUtils.java:
 *      Field templates are used in relation to multiple value lookups.  When doing a MV lookup on a collection, the
 *      returned BOs are not necessarily of the same type as the elements of the collection. Therefore, a means of
 *      mapping between the fields for the 2 BOs are necessary. The template attribute of <maintainableField> contained
 *      within <maintainableCollection> tells us this mapping.
 *      Example:
 *          <maintainableField name="collectionAttrib" template="lookupBOAttrib"> means that when a list of BOs are
 *          returned, the lookupBOAttrib value of the looked up BO will be placed into the collectionAttrib value of the
 *          BO added to the collection
 * webUILeaveFieldFunction - The name of a javascript function to called when when the user tabs out of the field.
 * webUILeaveFieldCallbackFunction - This is the call javascript function related to the webUILeaveFieldFunction.
 * readOnlyAfterAdd - This is used to indicate that the field is read-only after the record has been initially created.
 *
 * @deprecated Use {@link org.kuali.rice.krad.uif.field.Field} subclasses.

     * Single value lookups expect field conversions to be passed in as a HTTP parameter when the lookups is invoked from a quickfinder icon (i.e. magnifying glass on page).
                        Field conversions are normally used to determine which fields will be returned when the "return value" link is clicked.

                        For example, if we're performing a quickfinder lookup and the field conversion string "a:document.someObject.a1,b:document.someObject.b1" is passed into the lookup,
                        this means that when we click on a lookup result row to be returned:

                        * the value of property "a" from the selected result bo will be passed as the value of the HTTP parameter named "document.someObject.a1",
                          which, in turn, populates the POJO property of the same name on the form
                        * the value of property "b" from the selected result bo will be passed as the value of the HTTP parameter named "document.someObject.b1",
                          which, in turn, populates the POJO property of the same name on the form

                        Normally, the field conversion string is automatically computed by the framework to return all of the primary key values of the looked up BO into the corresponding
                        foreign key values of the destination BO (i.e. document.someObject in the example above).  However, putting in this element will allow for the overriding of the
                        field conversions string.
