Title:

Chapter 8 says that a STR may be used to reference an SCT, but does not
specify what reference types may be used as was done in the WSS Token
Profiles. In particular there are use cases for referencing an SCT by
its wsc:Identifier value.

Description:

The example in Chapter 8 shows a reference being made using a wsu:Id,
but the text does not really specify what is allowed or not allowed. For
example, can an Absolute URI be used or only a relative one.

There are a number of usecases where it would be desirable to reference
an SCT by its wsc:Identifier value.

1. When the SCT is only conveyed in the first message, especially if
there is more than one context active.

2. When reference is made from the Body or other Header element to the
SCT it is desirable to have a message-independent means of referencing
the SCT.

Related issues:

Issue 76, perhaps.

Proposed Resolution:

Perhaps use a direct reference for absolute and relative URIs and use a
KeyIdentifier to indicate the use of a wsc:Identifier value.
