Amaya as an RDFa editor?

Irene,

I tried to experiment with Amaya, trying to use it as an editor for an 
XHTML+RDFa file. And I failed...:-(

I tried to edit the file at [2]. It is a simple RDFa file; what is 
important to note that this file _validates_ using the XHTML+RDFa 
DTD[3]. However, if I edit this file with Amaya, as if it was an HTML 
file, when saving the file all properties that are RDFa specific and not 
in XHTML are removed from the generated file:-(

Is there a way to extend Amaya easily to properly manage an XHTML+RDFa 
file (based on its DTD)? Or is this so deeply in the code that this 
would require way too much work?

Thanks

ivan
