A reference from a realized feature to a program design that governs it, qualifiedby the kind of governing relationship and when it took effect. Use a bareprogramDesignRef where a feature has exactly one governing design in its original,as-built role; use this object where more than one design governs it, or where alater design supersedes an earlier one.
Database handle for the object. It is of XML type ID, so is constrained to beunique in the XML document within which it occurs. An external identifier for the object inthe form of a URI may be constructed using standard XML and XPointer methods. This is doneby concatenating the URI for the document, a fragment separator, and the value of the idattribute.
