+1 to everything Ben said that I snipped and importantly the above.

Subversion's versioning guarantees should only apply to itself, not it's
dependencies. Subversion isn't a platform - just one cog in the puzzle.
We can't freeze our dependencies and enforce our compatibility rules on
them. We can do our best to mitigate the effects, but a SVN major version
bump because a dependency had one? Eek.

FWIW, we're using httpd-2.1 HEAD with the SVN 1.0.x branch on
svn.apache.org without any problems. So, saying that SVN works only with
httpd-2.0.x and APR 0.9 isn't going to fly there. ;-) -- justin
