What drove me to build RxML was, first, the desire to be able to quickly 
and adhocly make RDF assertions in a wide variety of contexts: in plain 
text, comments in source code, arbitrary XML, etc. Second, to enable 
someone with the skill level, of, say, a html coder who can tweak PHP 
scripts, to author RDF without an extensive learning curve -- from my 
experience this is not possible with the standard XML serialization (or 
even N3).

I think until it becomes (nearly) as easy to develop in RDF as in XML it 
will be difficult for the semantic web to attain critical mass.  This is 
the broader motivation for the whole Rx4RDF project: allowing XPath, 
XSLT, etc. to work directly on a RDF model brings us closer to that goal 
-- both in terms of learning curve and ability to utilize existing 
tools, etc.
