ISSUE-3: metadata element and element content

metadata content model

metadata element and element content

State:
CLOSED
Product:
TTML 1.0
Raised by:
Philippe Le Hégaret
Opened on:

Description:
Currently the specification allows elements to have zero to n metadata class children elements. And that the ttm: namespace elements not have to be nested within a <metadata> parent. It has been suggested that it would be cleaner syntactically (without changing the semantics), to restrict elements to at most one <metadata> child element (as <tt> is restricted to at most one head element), and that ttm: elements be nested within a <metadata> parent.

e.g. to require:
<body>
<metadata>
<dc:xxx> </dc:xxx>
<ms:yyy> </ms:yyy>
<ttm:title>example</ttm:title>
</metadata>
...
</body>

As opposed to (would become ill formed):

<body>
<metadata>
<dc:xxx> </dc:xxx>
</metadata>
<ttm:title>example</ttm:title>
<metadata>
<ms:yyy> </ms:yyy>
</metadata>
...

Should elements be restricted to a single <metadata> child?
