	I believe the key part of the RDF/XML specification that applies is the following text:</p>
<p>
	<span style="color: rgb(0, 0, 0); font-family: sans-serif; font-size: medium; ">Relative URI references are resolved into&nbsp;</span><a href="http://www.w3.org/TR/2004/REC-rdf-concepts-20040210/#dfn-URI-reference" style="color: rgb(102, 0, 153); font-family: sans-serif; font-size: medium; ">RDF URI references</a><span style="color: rgb(0, 0, 0); font-family: sans-serif; font-size: medium; ">&nbsp;according to the algorithm specified in</span><a href="http://www.w3.org/TR/2001/REC-xmlbase-20010627/" style="color: rgb(102, 0, 153); font-family: sans-serif; font-size: medium; ">XML Base</a><span style="color: rgb(0, 0, 0); font-family: sans-serif; font-size: medium; ">&nbsp;</span><a href="http://www.w3.org/TR/REC-rdf-syntax/#ref-xml-base" style="color: rgb(102, 0, 153); font-family: sans-serif; font-size: medium; ">[XML-BASE]</a><span style="color: rgb(0, 0, 0); font-family: sans-serif; font-size: medium; ">&nbsp;(and RFC 2396)</span></p>
<p>
	<span style="color: rgb(0, 0, 0); font-family: sans-serif; font-size: medium; ">RFC 2396 (</span>http://www.ietf.org/rfc/rfc2396.txt)&nbsp;<span style="color: rgb(0, 0, 0); font-family: sans-serif; font-size: medium; ">is a document which discusses various properties of URIs, the section of interest is 5.1 which specifies how the Base URI is determined and allows the Base URI to be application determined</span></p>
<p>
	<span style="color: rgb(0, 0, 0); font-family: sans-serif; font-size: medium; ">This would imply that our behaviour is acceptable since we are using an application defined Base URI when invoked one way but not another. &nbsp;The fix may actually be to be consistent in our behaviour in this regard when invoking parsers directly with a filename and a graph.</span></p></td>
