== TTML Named Item Registry ==

=== Overview ===
The [https://www.w3.org/TR/ttml2/#metadata-vocabulary-item <code>ttm:item</code>] element can be used to
express arbitrary metadata that applies to a parent element.

This page provides a registry for [https://www.w3.org/TR/ttml2/#metadata-value-item-name <code><item-name></code>] values in order to promote interoperability.

== Standard TTML Item Names ==
* [[TTML/altText|altText]]
* [[TTML/usesForced|usesForced]]

The above values are standard values, defined by TTML2 unqualified by a namespace. Note that all other values unqualified by a namespace are reserved for standardization.

== Custom TTML Roles ==

Any future item name values will be added to this registry below.

There are currently no additional values in this registry.
