Yes, it is. Quite useful to create combined RelaxNG + Schematron schemata =)
But the reverse is not true. You need to extract the RelaxNG schema to allow 
validation with it.

I haven't looked in a while, but last time I checked, RelaxNG validation in 
libxml2 was somewhat suboptimal, so you might want to go a different way. (To 
specify, valid/invalid was usually fine, but the error reporting in the invalid 
case was very buggy as soon as the RelaxNG schema got more complex).
