Hi,
Here is some dummy code to what I think Johannes means:

<earl:Location rdf:id="...">

</rdf:li>

<earl:Location rdf:id="...">

<earl:xpath>path/to/image/2</earl:xpath>
<earl:line .../>

</rdf:li>
</rdf:Bag>
</earl:Location>
<earl:Location rdf:id="...">
<rdf:Bag>
<rdf:li>
<earl:xpath>path/to/image/3</earl:xpath>
<earl:line .../>
....
</rdf:li>
</rdf:Bag>
</earl:Location>

<earl:Location rdf:id="...">
<rdf:Bag>
<rdf:li>
<earl:xpath>path/to/link/1</earl:xpath>
<earl:line .../>
....
</rdf:li>
<rdf:li>
<earl:xpath>path/to/link/2</earl:xpath>
<earl:line .../>
....
</rdf:li>
</rdf:Bag>
</earl:Location>
So the idea is that each "Location" defines one instance of an error. A "Location" may be a composite of several resources that together trigger one instance of an error.
This approach makes good sense to me, what do others think of it?
Regards,
Shadi
