/**
 * Note on the layer mix with symbolic/ID-based interface:
 * You create a new layer with
 *    pLayerAdmin->NewLayer("A new layer");
 * This layer is automatically appended to the end of the list.
 *
 * The same holds true for layer sets.
 *
 * The interface for SdrLayerSet is based on LayerIDs. The app must get
 * an ID for it at the SdrLayerAdmin, like so:
 *   SdrLayerID nLayerID=pLayerAdmin->GetLayerID("A new layer");
 *
 * If the layer cannot be found, SDRLAYER_NOTFOUND is returned.
 * The methods with the ID interface usually handle that error in a
 * meaningful way.
 * If you not only got a name, but even a SdrLayer*, you can get the ID
 * much faster via the layer directly.
 *
 * @param bInherited:
 * TRUE If the layer/layer set cannot be found, we examine the parent layer admin,
 *      whether there's a corresponding definition
 * FALSE We only search this layer admin
 *
 * Every page's layer admin has a parent layer admin (the model's). The model
 * itself does not have a parent.
