+/**
+ * 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.
