What sort of relative URIs should be used.

    <dt>network
    <dd>network paths e.g. "//example.org/foo" omitting the URI scheme

To switch off relative URIs use the value "".
    Relative    URIs of any of these types are output where possible if
 and only if the option has been specified.

  The default behaviour only gives an XML Declaration when
  asked to write to an OutputStreamWriter that uses some
  encoding other than UTF-8 or UTF-16. 
In this case the encoding is shown
  in the XML declaration.
To ensure that the encoding attribute is shown in the XML declaration
either use the <code><b>write(Model,Writer,String)</b></code>
variant with an appropriate OutputStreamWriter or set this option
to false write the declaration to an OutputStream before calling
<code><b>write(Model,OutputStream,String)</b></code>.

 For the basic writer (RDF/XML) only
