/**
 * section: xmlWriter
 * synopsis: use various APIs for the xmlWriter
 * purpose: tests a number of APIs for the xmlWriter, especially
 *          the various methods to write to a filename, to a memory
 *          buffer, to a new document, or to a subtree. It shows how to
 *          do encoding string conversions too. The resulting
 *          documents are then serialized.
 * usage: testWriter
 * test: testWriter && for i in 1 2 3 4 ; do diff $(srcdir)/writer.xml writer$$i.tmp || break ; done
