ISSUE-149: XML schema error for tts:extent usage

XML schema error for tts:extent usage

State:
CLOSED
Product:
TTML 1.0
Raised by:

Opened on:

Description:
There is an error in the TTML XML schema regarding the use of
tts:extent.

TTML 1.0 says in the definition of extent that it is permitted on both
<region> and <tt> elements:

http://www.w3.org/TR/ttaf1-dfxp/#style-attribute-extent

However, the schema both forbids it on <tt>, and allows it on <body>:

http://www.w3.org/TR/ttaf1-dfxp/#dfxp-schema-xsd

Since the prose takes precedence, the schema should be corrected
and brought into conformance.
