* @class Ext.form.BasicForm
* @extends Ext.util.Observable
* <p>Encapsulates the DOM <form> element at the heart of the {@link Ext.form.FormPanel FormPanel} class, and provides
* input field management, validation, submission, and form loading services.</p>
* <p>By default, Ext Forms are submitted through Ajax, using an instance of {@link Ext.form.Action.Submit}.
* To enable normal browser submission of an Ext Form, use the {@link #standardSubmit} config option.</p>
* <p><b><u>File Uploads</u></b></p>
* <p>{@link #fileUpload File uploads} are not performed using Ajax submission, that
* is they are <b>not</b> performed using XMLHttpRequests. Instead the form is submitted in the standard
* manner with the DOM <tt><form></tt> element temporarily modified to have its
* <a href="http://www.w3.org/TR/REC-html40/present/frames.html#adef-target">target</a> set to refer
* to a dynamically generated, hidden <tt><iframe></tt> which is inserted into the document
* but removed after the return data has been gathered.</p>
* <p>The server response is parsed by the browser to create the document for the IFRAME. If the
* server is using JSON to send the return object, then the
* <a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.17">Content-Type</a> header
* must be set to "text/html" in order to tell the browser to insert the text unchanged into the document body.</p>
* <p>Characters which are significant to an HTML parser must be sent as HTML entities, so encode
* "<" as "&lt;", "&" as "&amp;" etc.</p>
* <p>The response text is retrieved from the document, and a fake XMLHttpRequest object
* is created containing a <tt>responseText</tt> property in order to conform to the
* requirements of event handlers and callbacks.</p>
* <p>Be aware that file upload packets are sent with the content type <a href="http://www.faqs.org/rfcs/rfc2388.html">multipart/form</a>
* and some server technologies (notably JEE) may require some custom processing in order to
