<metadata>

Description

Specifies general information about the SSML document rather than specifying the document's content, by using a metadata schema.

Although any metadata schema can be used with <metadata>, it is recommended that the Resource Description Framework (RDF) schema be used in conjunction with the general metadata properties defined in the Dublin Core Metadata Initiative.

The <metadata> element can have arbitrary content, although none of the content will be rendered by the synthesis processor.

Note: A <metadata> element exists as well for grammars.

Syntax

<metadata>
  RDF schema
</metadata>

Parents

<audio>, <choice>, <enumerate>, <foreach>, <prompt>, <speak>

Children

CDATA, #PCDATA

Limitations/Restrictions

• <metadata> is only supported as a child of <foreach> when <foreach> is used within <prompt>.
• Refer to your vendor documentation for support details.

Example

To include speech markup tags, insert the SSML tags inside one of the <prompt>, <audio>, <choice>, <enumerate>, or <foreach> (within <prompt>) elements.
