It has been used in  unix for some time now.  $1$SEED$HASH is MD5; 
depending upon what OS you use the number differs in the hash.  Years 
ago I rewrote crypt for FreeBSD to use $3$ for SHA1.  I know Redhat is 
now using $6$ for a form of SHA, I don't know which one.

Where is the standard that defines what the hash format is for the 
various {types} ?

This is basically to make migration easier, if I could reformat a 
"$1$seed$hash" into "{SMD5}hashseed"? and stuff it into userPassword, 
the users have no disruption.
