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

- 2008-12-03
- 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? - Related Actions Items:
