Preserving subtitles

Dear All
I'm a total newbie to this schema and was wondering if you could help me 
better understand it?!  We are currently implementing a new system which 
outputs subtitles in Timed Text Markup Language (TTML) 1.0 (Second 
Edition). Is this the standard language used for preservation purposes? 
  Also in the sample output I've received there are things like # (hash) 
at the start of a line which I think stands for singing rather than just 
spoken e.g.
<p begin="123.84"># The Lingo Show, The Lingo Show</p>

Also another line of text is in capital letters which seems to describe 
non-dialog audio e.g.
<p begin="181.64">BUZZER SOUNDS</p>

What I wanted to know is are the above standard formatting within TTML 
or is this specific to our system?  I have had a look at the following 
but can't seem to find reference to the above.

Any guidance would be very much appreciated.
