* @param suggestion
* When the content tree has a suggestion for the prefix

* parameter. Typicall this value comes from the QName.getPrefix
* to show the preference of the content tree. This parameter
* may be null, and this parameter may represent an already

* @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 prefered 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.
