What you are asking for is this, I think:

% git checkout A % cat table.xml <table A> % echo "<table A v2>" > table.xml % git commit -a -m "fix table on Branch A"

% git checkout B % cat table.xml <table B> % echo "<table B v2>" > table.xml % git commit -a -m "fix table on Branch B"

% git checkout master % cat table.xml <non-version-specific table info> % cat process.bpel main line process stuff % echo "add more process stuff" >> process.bpel % git commit -a -m "fix process stuff on mainline"

% git checkout A % git merge master % cat process.bpel main line process stuff add more process stuff

% git checkout B % git merge master % cat process.bpel main line process stuff add more process stuff

Is that not it?
