Hi,
This question is unrelated to Subversion's usage or issues, but
related to version control model of Subversion source code. Let
me explain in detail.
As far as I know, new code is committed to trunk firstly, then
cherry-picked to release-branch in necessary, so the branch-view
of Subversion is following (cp stands for cherry-pick):
-----------o--------------------o----------- 1.10.x
/ /
cp cp
/ /
--------o---------o--------o---------o-----o trunk
\ \ \
cp cp cp
\ \ \
------------o---------o-------------------o 1.11.x
And tags are always created on release-branch.
Am I right?
