The Time-Markers i.e. T0, T1, T2 and so on, are used by the NVBG to mark each individual word in the sentence and later it can use this information to play animations at the start/end of that word.

e.g. in the above output bml, the animation "HandsAtSide_Arms_GestureWhy" is timed to play at sp1:T3, which means it will be played when the word "on" has been spoken. 'sp1' is the id of the speech tag which indicates that this 'T3' is from this particular speech tag. (currently NVBG only supports one speeech tag).

The appropriate "vrAgentSpeech partial" event messages are sent out by smartbody after each word has been spoken by the character. e.g."vrAgentSpeech partial 1337363228078-9-1 T19 Depending on the default voice you have selected in Windows," is sent out after the word Windows is spoken.

Similarly the <head> tag is interpreted by smartbody to generate Nods and other specified behavior.

The "priority" attribute allows NVBG to decide which behavior is to be culled if any of the behaviors overlap. This is done before the final message is sent out.
