     \section1 Filtering
 
-    In addition to sorting, QSortFilterProxyModel can be used to hide
-    items that don't match a certain filter. The filter is specified
-    using a QRegExp object and is applied to the filterRole()
-    (Qt::DisplayRole by default) of each item, for a given column.
-    The QRegExp object can be used to match a regular expression, a
-    wildcard pattern, or a fixed string. For example:

-    \bold{Note:} Some general guidelines for subclassing models are
-    available in the \l{Model Subclassing Reference}.
-
     Since QAbstractProxyModel and its subclasses are derived from
-    QAbstractItemModel, much of the same advice about subclassing normal
-    models also applies to proxy models. In addition, it is worth noting
-    that many of the default implementations of functions in this class
-    are written so that they call the equivalent functions in the relevant
-    source model. This simple proxying mechanism may need to be overridden
-    for source models with more complex behavior; for example, if the
-    source model provides a custom hasChildren() implementation, you
-    should also provide one in the proxy model.
