Description

A thing we always found quite annoying is that the SDOXMLWriter prints NS prefixes like tns1: etc ... which is technically OK, but not nice.
When saving a SDO, the SDOXMLWriter dynamically collects all NS in a map in a way that it adds a NS/prefix pair only, if not yet in (by URI).

This feature could be used nicely, by

• adding a method registerNamespace() to XMLHelper
• XMLHelperImpl maintains a map just like SDOXMLWriter
• whenever XMLHelperImpl is asked to save a SDO, it passes this map on to the instance of SDOXMLWriter
  using SDOXMLWriter.addNamespace() which is private currently though
  Then, SDOXML just goes on like today collecting the NS ... but then, when actually printing it uses the NS prefixes supplied by the user (or not, depending whether the needed NS was in or not).
