Sharing gnucash account files between users

[Ronan KERYELL]

I'm thinking about sharing some account files for some research projects
between several users with a version control system such as subversion.

Since gnucash files are in XML, I expect it can be possible with some
careful merges in the case of conflicting writes (well, if we ask
"uncompress mode" in the prefs :-) ).

Does it make sense?

Are there some subtle invariants we should ensure?

I've encountered this one:
<gnc:count-data cd:type="account">114</gnc:count-data>
<gnc:count-data cd:type="transaction">315</gnc:count-data>
that seems easy to manage.

Can I expect the unique-ID-like such as
       <split:id type="guid">d460704ada6fbde0e08c7a7cd71a608f</split:id>
everywhere are sensibly random and are not, for example, a function of the old
file state, in which case 2 futures of the same file would pick the same
unique ID and we would always need to deal with non unique ID...
