* Returns a preferred prefix for the given namespace URI;

*
* This method is intended to be overrided by a derived class.
*
* @param namespaceUri
* The namespace URI for which the prefix needs to be found.
* Never be null. "" is used to denote the default namespace.
* @param suggestion
* When the content tree has a suggestion for the prefix
* to the given namespaceUri, that suggestion is passed as a
* parameter. Typically this value comes from QName.getPrefix()
* to show the preference of the content tree. This parameter
* may be null, and this parameter may represent an already
* occupied prefix.
* @param requirePrefix
* If this method is expected to return non-empty prefix.
* When this flag is true, it means that the given namespace URI
* cannot be set as the default namespace.
*
* @return
* null if there's no preferred prefix for the namespace URI.
* In this case, the system will generate a prefix for you.
*
* Otherwise the system will try to use the returned prefix,
* but generally there's no guarantee if the prefix will be
* actually used or not.
*
* return "" to map this namespace URI to the default namespace.
* Again, there's no guarantee that this preference will be
* honored.
*
* If this method returns "" when requirePrefix=true, the return
* value will be ignored and the system will generate one.

/**
* Returns a list of namespace URIs that should be declared
* at the root element.
*
* By default, the JAXB RI produces namespace declarations only when
* they are necessary, only at where they are used. Because of this
* lack of look-ahead, sometimes the marshaller produces a lot of
* namespace declarations that look redundant to human eyes. For example,
*
* <?xml version="1.0"?>
* <root>
* <ns1:child xmlns:ns1="urn:foo"> ... </ns1:child>
* <ns2:child xmlns:ns2="urn:foo"> ... </ns2:child>
* <ns3:child xmlns:ns3="urn:foo"> ... </ns3:child>
* ...
* </root>
* <xmp></pre>
* <p>
* If you know in advance that you are going to use a certain set of
* namespace URIs, you can override this method and have the marshaller
* declare those namespace URIs at the root element.
* <p>
* For example, by returning <code>new String[]{"urn:foo"}</code>,
* the marshaller will produce:
* <pre><xmp>
* <?xml version="1.0"?>
* <root xmlns:ns1="urn:foo">
* <ns1:child> ... </ns1:child>
* <ns1:child> ... </ns1:child>
* <ns1:child> ... </ns1:child>
* ...
* </root>
* <xmp></pre>
* <p>
* To control prefixes assigned to those namespace URIs, use the
* {@link #getPreferredPrefix} method.
*
* @return
* A list of namespace URIs as an array of {@link String}s.
* This method can return a length-zero array but not null.
* None of the array component can be null. To represent
* the empty namespace, use the empty string <code>""</code>.
*
* @since
* JAXB RI 1.0.2
