/**
* Resolves relative references among {@link SDDocument}s.
*
*
* This interface is implemented by the caller of
* {@link SDDocument#writeTo} method so
* that the {@link SDDocument} can correctly produce references
* to other documents.
*
*
* This mechanism allows the user of {@link WSEndpoint} to
* assign logical URLs to each {@link SDDocument} (which is often
* necessarily done in a transport-dependent way), and then
* serve description documents.
*
*
*
*
Usage Example 1
*
* HTTP servlet transport chose to expose those metadata documents
* to HTTP GET requests where each {@link SDDocument} is identified
* by a simple query string "?ID". (HTTP servlet transport
* assigns such IDs by itself.)
*
*
* In this nameing scheme, when {@link SDDocument} X refers to
* {@link SDDocument} Y, it can put a reference as "?IDofY".
* By implementing {@link DocumentAddressResolver} it can do so.
