Info on Radio Directory API XML

[lucasmdo]

Hi!

I'm currently playing around with SHOUTcast's Radio Directory API, and even though the information is quite clear on the API, I have a doubt regarding some info returned on the XML.

code:
<station name="Dj Wouner- Radio Fusion-A novidade come?a Aqui!-[SHOUTcast.com]" mt="audio/mpeg" id="139549" 

    br="64" genre="Various"ct="Rihanna Feat. Chris Brown & Jay-Z - Umbrella" lc="614" ml="2100" nsc="No" cst=""/>

What does 'ml', 'cst' and 'nsc' represent?

Thanks in advance!
