From Dave Burke March 21:

o Element <needmoredata> not specified in the text but is specified in schema. 
Obviously needed for training voiceprints. Note it should be called <need-more-
data> for consistency. Why not have it as a childless element instead of 
containing a boolean - its presence implies more data needed?
Shouldn't <need-more-data> be at the same level as <cumulative> and 
<incremental> as opposed to being duplicated in both? Or at least just be 
contained in <cumulative>?

<DanB> I believe this was removed from the text at some point, but I'm not 
sure why.  Can anyone comment on this? </DanB>
