Each feature has its own section. We need to add #profile as a feature in SDP-US, and use the elements defined in TTML. Each feature has a section with such a table. 

Thanks.

Implemented original proposal at http://dvcs.w3.org/hg/ttml/rev/108c8bf20b6d.


However, I don't understand the editing instructions below for an updated proposal. Please be more specific regarding "adding a table" and its contents.

Updated proposal to close Issue-182 and Action-117.

Addresses concerns raised by TTWG Oct 18 to add elements required to support ttp:profile element as defined in TTML 1.0.

Add a table for #profile as a required SDP-US feature.
1. Add #profile feature.
2. Set Usage Type as required.
3. Add under Context of Use:
        profile
        features
        feature
        extensions
        extension

No other restrictions apply.

Subject: Update to Issue-182 Proposal

Here is an updated proposal that replaces the initial proposal in Issue-182: http://www.w3.org/AudioVideo/TT/tracker/issues/182.


Section 1
Change from: Claims of conformance MUST use this URI and implement the required features and constraints of use and processing outlined in this profile.
Change to:
Claims of document conformance MUST use this URI defined in this profile.
Claims of presentation processor conformance MUST implement the required features and constraints of use and processing outlined in this profile.

Add 2nd bullet to this sentence:
Conformance to this profile does not preclude the:
*       Use of other features defined in TTML 1.0. Such behavior is not defined here.
*       Use of other profiles that may implement the features in this profile.

Section 5.4.2
Add to Note (1). NOTE: See also Conformance.  TTML 1.0 allows zero or more profiles (ttp:profile in the head element) to be specified and used simultaneously. A presentation processor may reject documents it does not understand.

Add to Note (2). NOTE: When the use attribute is used on the ttp:profile element could indicate the geographical region for which the profile is used. For example, specific styling capabilities could be used in a particular geographical region. See also Other Constraints.

Requirement R0007
Add ttp:profile element.

Add in Error Handling section:
Note: A presentation processor is not required to reject a document if the profile URI is not recognized. A document is rejected if it contains an unknown required feature and the presentation processor does not implement that feature.
