Description

Selecting from an unbound graph is being ignored by all resolvers. This should not be ignored by the the XAResolver.

example:

select $s $p $o $g from <rmi://localhost/server1#>
where $s $p $o $g;


logs:
<pre>
2008-04-17 09:55:20,647 WARN  XSDResolver - Ignoring solutions for [$s $p $o $g]
2008-04-17 09:55:20,669 WARN  [[PrefixResolver]] - Ignoring solutions for [$s $p $o $g]
2008-04-17 09:55:20,673 WARN  [[LuceneResolver]] - Ignoring solutions for [$s $p $o $g]
</pre>

Also, prebinding the graph is also being ignored. This is a real issue as it does not allow for graph selection by property.

example:
<pre>
select $s $p $o $g from <rmi://localhost/server1#>
where $g <rdf:type> <mulgara:Model> and $s $p $o $g;
</pre>

*or*

<pre>
select $s $p $o $g from <rmi://localhost/server1#>
where $s $p $o $g and $g <rdf:type> <mulgara:Model>;
</pre>
<pre>
