XML is based upon Unicode, and there are serious problems in
defining case when you take into account all of the writing systems
in use across the world. The XML working group felt that the
complexity involved would make it inappropriate to require support
in all implementations. The natural consequence was a decision to
make tags and attributes sensitive to case.

If you are editing XML by hand it is easy to violate
well-formedness. (You can see this from the HTML on the Web).
As a result, it makes a lot of sense to use a tool that will
help to ensure that you haven't inadvertently slipped up.
Such a tool can make the task of getting the case right into
trivial operation. See HTML Tidy for example of such a tool.
