Why do you say XML cannot be merged? All the XML I have worked with has
been as mergeable as source code - i.e. mostly trivial changes in
unrelated areas of the file; sometimes conflicts in the same area of the
file which hopefully will get caught and flagged by the merge tool (but
occasionally will result in duplicate sections of code). If the merge
tool didn't make any attempt, I would end up using a diff tool to do the
merge by hand - but I would most definitely be doing a merge.

Of course, there always the chance of tools getting confused - I always
check and test after the merge before checking in. But that goes for
all text document types - .c, .h, .pl, ...

I'm with Curtis on this one - I would like my XML to be treated as text.
