Forms are key components in VoiceXML applications. Forms collect user input and present information to the user. A form can define a field item (for collecting user input), or a control item (contains procedural items to help collect inputs).
<form id="String" scope="dialog" | "document" cleardtmf="true" | "false"> child elements </form>
| id | The id attribute defines the name of the form. If specified, it can be referenced within the same document or from another document. e.g. <form id=“hello”> can be referenced as <goto next=“#hello”/>. This attribute is optional. |
| scope | The scope attribute defines the scope of the form’s grammar. This attribute is optional and defaults to dialog. dialog – the form’s grammars are only active within the form. document – the form’s grammars are active throughout the document. If this is an application root document, then the form grammars are active throughout the application. |
