A synthetic revision that represents the initial period of an object in a
branch when the object is
still associated with a revision from one of the baseline branches. It always has version
zero and can only appear in branches below the
main branch.
Synthetic revisions are used for two slightly different purposes:
- For
cacheoptimization. - As a persistent "detach marker" indicating that the first modification of an object in a branch is its deletion.
Instances of this marker revision are not supposed to be exposed outside of a revision manager. They are mainly used in the communication between a revision manager and its associated revision
loader.
