carets in an EDI are for breaking out data within asterisk-separated data within tilde-separated data

In an ST*834 EDI file callouts of data between ST* and SE* include:

1. NM1* for names. This suggests the next few bits of information correspond to what you might think of as a name "object" in Java or C#.
2. INS* is for a similar insurance "object" which is going to have different properties that are related to the same concept.
3. DTP* is for dates and there will be a number following DTP* which is a lookup code for what the date means, its context.
