-<p>It is possible to change a JsonReader's metadata at any time by including a
-<b><tt>metaData</tt></b> property in the data object. If this is detected in the
-object, a <a ext:cls="Ext.data.Store" href="output/Ext.data.Store.html">Store</a> object using this Reader will reconfigure
-itself to use the newly provided field definition and fire its
-<a ext:cls="Ext.data.Store" ext:member="metachange" href="output/Ext.data.Store.html#metachange">metachange</a> event. In
-undergoing this change, the Store sets its <a ext:cls="Ext.data.Store" ext:member="sortInfo" href="output/Ext.data.Store.html#sortInfo">sortInfo</a> property
-from the <tt>sortInfo</tt> property in the new metadata. Note that reconfiguring a Store
-potentially invalidates objects which may refer to Fields or Records which no longer exist.</p>
-<p>The <b><tt>metaData</tt></b> property may contain any of the configuration
-options for this class. Additionally, it may contain a <b><tt>fields</tt></b>
-property which the JsonReader will use as an argument to <a ext:cls="Ext.data.Record" ext:member="create" href="output/Ext.data.Record.html#create">Ext.data.Record.create</a>
-to configure the layout of the Records which it will produce.<p>
-Using the <b><tt>metaData</tt></b> property, and the Store's <a ext:cls="Ext.data.Store" ext:member="metachange" href="output/Ext.data.Store.html#metachange">metachange</a> event,
-it is possible to have a Store-driven control initialize itself. The metachange
-event handler may interrogate the <b><tt>metaData</tt></b> property (which
-may contain any user-defined properties needed) and the <b><tt>metaData.fields</tt></b>
+<p><b><u>Automatic configuration using metaData</u></b></p>
+<p>It is possible to change a JsonReader's metadata at any time by including
+a <b><tt>metaData</tt></b> property in the JSON data object. If the JSON data
+object has a <b><tt>metaData</tt></b> property, a <a href="output/Ext.data.Store.html" ext:cls="Ext.data.Store">Store</a>
+object using this Reader will reconfigure itself to use the newly provided
+field definition and fire its <a href="output/Ext.data.Store.html#Ext.data.Store-metachange" ext:member="metachange" ext:cls="Ext.data.Store">metachange</a>
+event. The metachange event handler may interrogate the <b><tt>metaData</tt></b>
property to perform any configuration required.</p>
-<p>To use this facility to send the same data as the above example without
-having to code the creation of the Record constructor, you would create the
-JsonReader like this:</p><pre><code>var myReader = <b>new</b> Ext.data.JsonReader();</code></pre>
+<p>Note that reconfiguring a Store potentially invalidates objects which may
+refer to Fields or Records which no longer exist.</p>
+<p>To use this facility you would create the JsonReader like this:</p><pre><code><b>var</b> myReader = <b>new</b> Ext.data.JsonReader();</code></pre>
<p>The first data packet from the server would configure the reader by
-containing a metaData property as well as the data:</p><pre><code>{
+containing a <b><tt>metaData</tt></b> property <b>and</b> the data. For
+example, the JSON data object might take the form:</p><pre><code>{
