Yes. The OWL API reads OWL 1.0 documents and can write OWL1.1  
documents. Protege will in fact do this.

IIRC, there are some issues remaining (esp. involving declarations).

I also started on an XSLT that would go from the XML syntax to either  
1.1 RDF/XML or (if posssible) OWL 1.0 RDF/XML.

Others have answered, but I'll also point to the OWLED wiki page:

It's a bit out of date. I posted a note saying we should migrate this  
to the OWLWG wiki, presuming that we can find a space that will be  
maintained ad infinitum.

TopBraid certainly does, and is entirely Jena based. Holger, on  
public-owl-dev Pellet has both OWL API and Jena front ends.

Here's the annoucement:
