What sort of relative URIs should be used.
A comma separate list of options:
<dl>
<dt>same-document
<dd>same-document references (e.g. "" or "#foo")
<dt>network
<dd>network paths e.g. "//example.org/foo" omitting the URI scheme
<dt>absolute
<dd>absolute paths e.g. "/foo" omitting the scheme and authority
<dt>relative
<dd>relative path not begining in "../"
<dt>parent
<dd>relative path begining in "../"
<dt>grandparent
<dd>relative path begining in "../../"
</dl>
The default value is "same-document, absolute, relative, parent".
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.

no XML declaration is included.
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>.

This declaration includes a !ENTITY declaration for each
prefix mapping in the model, and any attribute value that
starts with the URI of that mapping is written as starting
with the corresponding entity invocation. Warning:

>section-Reification</a>.
By default <a href="http://www.w3.org/TR/rdf-syntax-grammar#propertyAttr">propertyAttr</a>
is blocked.
For the basic writer (RDF/XML) only
<a href="http://www.w3.org/TR/rdf-syntax-grammar#parseTypeLiteralPropertyElt">parseTypeLiteralPropertyElt</a>
has any affect, since none of the other rules are implemented by that writer.
