A format somewhat inspired by HTML. The files in this format I've come across have for some reason been in a variety of text encodings. A sample extract:

<SAMI>
<HEAD>
<HEAD>
<TITLE></TITLE>
<STYLE TYPE="text/css">
<!--
P { margin-left:8pt; margin-right:8pt; margin-bottom:2pt; margin-top:2pt;
text-align:center;
font-size:20pt; font-family:arial, sans-serif; font-weight:normal; color:white; }
.ENCC { Name:English; lang:en-US; SAMIType:CC;}
#STDPrn { Name:Standard Print;}
#LargePrn { Name:Large Print; font-size:25pt;}
#SmallPrn { Name:Small Print; font-size:15pt;}
-->
</STYLE>
</HEAD>
<BODY>

<SYNC Start=40647><P Class=ENCC>
<SYNC Start=42315><P Class=ENCC>
A "shinigami" appears<br>from the eastern seas.

A second example excerpt showing how variable the files are:
