/**
 * @class Ext.data.XmlStore
 * @extends Ext.data.Store
 * 
Small helper class to make creating {@link Ext.data.Store}s from XML data easier.
 * A XmlStore will be automatically configured with a {@link Ext.data.XmlReader}.
 * 
A store configuration would be something like:

var store = new Ext.data.XmlStore({
    // store configs
    autoDestroy: true,
    storeId: 'myStore',
    url: 'sheldon.xml', // automatically configures a HttpProxy
    // reader configs
    record: 'Item', // records will have an "Item" tag
    idPath: 'ASIN',
    totalRecords: '@TotalResults'
    fields: [
        // set up the fields mapping into the xml doc
        // The first needs mapping, the others are very basic
        {name: 'Author', mapping: 'ItemAttributes > Author'},
        'Title', 'Manufacturer', 'ProductGroup'
    ]
});
 * 

 * 
This store is configured to consume a returned object of the form:

<?xml version="1.0" encoding="UTF-8"?>
<ItemSearchResponse xmlns="http://webservices.amazon.com/AWSECommerceService/2009-05-15">
    <Items>
        <Request>
            <IsValid>True</IsValid>
            <ItemSearchRequest>
                <Author>Sidney Sheldon</Author>
                <SearchIndex>Books</SearchIndex>
            </ItemSearchRequest>
        </Request>
        <TotalResults>203</TotalResults>
        <TotalPages>21</TotalPages>
        <Item>
            <ASIN>0446355453</ASIN>
            <DetailPageURL>
                http://www.amazon.com/
            </DetailPageURL>
            <ItemAttributes>
                <Author>Sidney Sheldon</Author>
                <Manufacturer>Warner Books</Manufacturer>
                <ProductGroup>Book</ProductGroup>
                <Title>Master of the Game</Title>
            </ItemAttributes>
        </Item>
    </Items>
</ItemSearchResponse>
 * 
 * An object literal of this form could also be used as the {@link #data} config option.

 * 
Note: Although not listed here, this class accepts all of the configuration options of 
 * {@link Ext.data.XmlReader XmlReader}.
 * @constructor
 * @param {Object} config
