Description
The <meta> tag is similar to the tag of the same name in HTML, it provides information about the page as a name/value pair. The value is specified in the content attribute. The name either corresponds to an HTTP response header field such as "Expires" or "Date", in which case the http-equiv attribute is specified, or a meta-data document property, in which case name is used.
HTTP header fields specified by http-equiv override fields which are sent by the server, which can be used for example to change the expiration date for the cache.
The VoiceXML standard recommends, but does not mandate, that properties with the following names be supported.
name="author", name of the author.
name="maintainer", the author's e-mail address. This might be used to generate a pager or e-mail notification in the event of an error on this page.
name="copyright", an intellectual property legal notice.
name="keywords", a set of keywords for the page.
name="description", a short description of the page for human readers.
name="robots", a description of the page formatted for search engines.
