No that's not happening, tags are skipped at once, just the text that's 
a child of <prompt> makes it to the TTS.

As I said, the tts only gets simple plain sentences. Second, I need to 
work on festival, since flite won't support languages other than English 
at the moment.
Third, festival can be accessed in server mode (via socket) or via the 
text2wave shell program, or, again, via festival_client (another shell 
executable) or, yet, via a perl script...

I'll investigate further, but as I said, vg will discard unknown tags 
from the SSML page returned by OVXI.
