There is no standard way of referencing a RelaxNG schema from an 
instance document. The reason for this is because it's considered bad 
practice to associate tightly a document with a schema, since in fact 
depending on the situation one could want to apply different schemata 
from the one the author thought would be the best.

So yes, the fact that the document begins with an <svg> element in the 
"http://www.w3.org/2000/svg" namespace is sufficient to indicate that 
it's a standalone SVG document (in fact, it's already sufficient today, 
though many still believe one has to specify the DOCTYPE).

It is also likely that we'll be putting an RDDL (http://rddl.org/) 
document at http://www.w3.org/2000/svg that will point to the RelaxNG, 
but that may require that we wait for the TAG to come to some decision 
on it.
