Why we have NULL txn_id for delta representation?

Hi,
I could see all 'delta' representations having TXN as 0. I could see the
code of subversion/libsvn_fs_base/reps-strings.c@18787:line 1544 causing
this behaviour.

Can someone clarify.

P.S I could see the mention of Representation's TXN acting as a kind of
mutablity flag. I think we clone only the 'nodes' entries for the path
getting changed not the representations, as we put the youngest as
'fulltext' so why we need to clone the corresponding representations
rather we can create new representations.

With regards
Kamesh Jayachandran
