The "data:text/plain" construct is not SMIL-specific, it is a URL 
scheme, just like http: or ftp:. It is described in RFC2397, 
<http://www.faqs.org/rfcs/rfc2397.html>. Officially you need to escape 
almost anything but alphanumeric characters, but lots of players are 
forgiving and will allow unescaped spaces and other characters.

Please note that QuickTime only supports SMIL 1.0, not 2.0. What you're 
doing in these lines of the document is you're stating in the DOCTYPE 
that it is a SMIL 1.0 document, but in the <smil> tag that the default 
namespace is the SMIL 2.0 namespace. Doctypes and namespaces always 
confuse me, so I'm hardly an expert on the matter, but I'm pretty sure 
this is not legal.

Uhm... I'm not sure...
There must be other SYMM WG members on this list who can answer this 
question, I hope?
