[Trennmuster] Questions to better understand prefix and suffix

[Pander]

Hi all,

I have some questions about the following. The look critical but are
only to really understand it all.

Hyphenation priority is:
1 -= hyphenation of compound's suffix, multiple = have higher priority
2 |= hyphenation of compound's prefix, multiple = have higher priority
3 =  hyphenation of compound, multiple = have higher priority
4 |  hyphenation of word's prefix, priority order is from left to right
5 -  hyphenation of word, multiple - have higher priority

There is a character to indicate a prefix |
There is a character combination to indicate a compound prefix |=
There is a character combination to indicate a compound suffix -=

1) Why is there a prefix character in the first place? Is it only to
prevent to many -'s?

Would otherwise
  abregte;ab|reg-te
simply be
  abregte;ab--reg-te
?

And
  vorbehaltlose;vor|be|halt--lo-se
would be
  vorbehaltlose;vor----be---halt--lo-se
Correct?

I see that it would result in many -'s

2) If there is no reason for |, then |= could be written as =- Correct?

3) If there is a reason why is there no character to indicate a suffix?
Is there no need for it?

A candidate could be

4) If you would introduce a suffix character, then you would also have
=¦ instead of -= This would make it more consistent and balanced.

Can you find examples of double suffix usage?
