Emacspeak And Ruby

Emacspeak now speech-enables ruby-mode to support developing Web applications using Ruby On Rails. I presently use nxml-mode for editing the .rhtml files, but am looking for an alternative to using multi-mode or its variants when editing the embedded Ruby code. Sadly, one has to turn off nxml-mode's validity checking while editing .rhtml files --- otherwise it complains about the <% directives.
