At the recent face-to-face it came to light that more prose was needed
around the id[1] and ref[2] attributes in the SOAP Encoding[3] section of
Part 2[4]

Specifically the uniqueness constraint needs to be made explicit. We cannot
refer to XML Schema for this, because the uniqueness constraint is defined
in XML Schema Part 1[5] as part of a validation episode and SOAP requires
that no such episodes be mandated.

I took an action item to send mail to open a new issue and also provide a
proposed resolution.

New Issue: Uniqueness and reference constraints of id and ref

Info: This issue is related to Issue 163

Proposed resolution;

Add the following text to Section 3 of Part 2

Constraints on id and ref attribute information items

The value of a ref attribute information item MUST also be the value of
exactly one id attribute information item
