# <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.
