Various ornaments, please help me

[胡海鹏 - Hu Haipeng]

Hello:
  I'm about help both Freedots and the Japanese project BrailleMuse to implement their musicxml to braille program (Valentin knows, one is an online server under an unknown license :-), and the other a GUI under GNU, but too young). My plan is, to write a score with many kind of notations using Lilypond, and then ask a person to type into Finale (I ever asked someone to do with Sibelius, but Dolet 4 for Sib is poorer), then I make the XML. Now I add a lot of signs, and encounter problems with various ornaments: I can't distinguish the following, because I can't find Chinese translations and coincident examples to listen:

don't know    known
prall         upmordent (or downmordent?)
prallprall    downmordent
prallmordent  --
upprall      upmordent
prallup
downprall    downmordent
pralldown
lineprall
signumcongruentiae  my god, what's this!?

  Could anyone please give me a description of the differences and meaning? If someone is an expert of Baroque ornaments, please write out the sound results.
  BTW, how to write "bebbung" (trembling) using Lilypond?
TIA!

Haipeng
