What are the proposed semantics of this multitreeselect?

If we imagine something like:

[ ] a
  [ ] a/b
  [ ] a/c
[ ] b
  [ ] b/a

Would checking "a" automatically also check "a/*"?
Is it only about UI, meaning "a/*" would be collapsed under "a"?
Shall it be possible to check "a", but uncheck "a/b"?

Timo
