Related notes:

EBU liaison has requested feature to allow document conformance to (zero to many) profiles to be described using short form aliases to allow references to specifications not wholly defined by schemas or feature designators, i.e. where behaviour is described normatively in documentation.

Proposal added on behalf of EBU:

* There should be a new element that signals standard conformance.
* This element has a lower bound of 1 and an upper bound of "unbounded".
* The standard is referenced by an URI.
* Conformance is not defined by an explicit profile mechanism but is
only defined by the prose of the referenced standard.
* The URI is an unique identifier and there is no strict requirement
that this resolves to a resources available (e.g. over http).

Example (for easier reading without namespaces):

<metadata>
<conformsToStandard>http://www.w3.org/ns/ttml</conformsToStandard>
<conformsToStandard>http://www.w3.org/ns/ttml/profile/imsc-text</conformsT
oStandard>
<conformsToStandard>urn:ebu:tt-d</conformsToStandard>
<conformsToStandard>http://www.w3.org/ns/ttml/profile/sdp-us</conformsToSt
andard>
</metadata>

The name of the element could be different.
