- (Optional) A path specification for use by the Ext.data.Reader implementation that is creating the Record to access the data value from the data object. If an Ext.data.JsonReader is being used, then this is a string containing the javascript expression to reference the data relative to the Record item's root. If an Ext.data.XmlReader is being used, this is an Ext.DomQuery path to the data item relative to the Record element. If the mapping expression is the same as the field name, this may be omitted.
