I will point you to some previous threads on this:

http://sourceforge.net/p/dotnetrdf/mailman/message/32563380/
http://sourceforge.net/p/dotnetrdf/mailman/message/32848471/

Basically what these thread says is that no you cannot make dotNetRDF
produce a particular RDF/XML output because we intentionally provide limited
configurability over the compression options in order to prefer correctness.

If you want to generate a particular RDF output then what you actually need
to do is to construct an appropriate graph.  For example to get a
<cim:ACLineSegment> element rather than a <rdf:Description> element then
your graph needs to contain appropriate rdf:type statements

The focus for any RDF producing/consuming application should be what triples
need to be expressed and not the serialisation (RDF/XML in your question)
since that is irrelevant to the actual problem (and if it is relevant then
your RDF system is IMO poorly designed)
