/**
- * @class Ext.data.TreeStore
- * @extends Ext.data.AbstractStore
- *
* The TreeStore is a store implementation that is backed by by an {@link Ext.data.Tree}.
* It provides convenience methods for loading nodes, as well as the ability to use
* the hierarchical tree structure combined with a store. This class is generally used
* in conjunction with {@link Ext.tree.Panel}. This class also relays many events from
* the Tree for convenience.
- *
- * ## Using Models
+ *
+ * # Using Models
+ *
* If no Model is specified, an implicit model will be created that implements {@link Ext.data.NodeInterface}.
- * The standard Tree fields will also be copied onto the Model for maintaining their state.
- *
- * ## Reading Nested Data
- * For the tree to read nested data, the {@link Ext.data.Reader} must be configured with a root property,
+ * The standard Tree fields will also be copied onto the Model for maintaining their state. These fields are listed
+ * in the {@link Ext.data.NodeInterface} documentation.
+ *
+ * # Reading Nested Data
+ *
+ * For the tree to read nested data, the {@link Ext.data.reader.Reader} must be configured with a root property,
* so the reader can find nested data for each node. If a root is not specified, it will default to
* 'children'.
