This is a filter which all Features immediately contained by this FeatureHolder will match. It need not directly match their child features, but it can (and should!) provide information about them using FeatureFilter.OnlyChildren filters. In cases where there is no feature hierarchy, this can be indicated by including FeatureFilter.leaf in the schema filter.
For the truly non-informative case, it is possible to return FeatureFilter.all. However, it is almost always possible to provide slightly more information that this. For example, Sequence objects should, at a minimum, return FeatureFilter.top_level. Feature objects should, as a minimum, return FeatureFilter.ByParent(new FeatureFilter.ByFeature(this)).
