But how do you know that? Maybe whitespace is significant in this case. For
example:

<JavaFormatOptions>
  <PrettyPrint>true</PrettyPrint>
  <IndentString>    </IndentString>
</JavaFormatOptions>

or

<UserList>
  <User>
    <Username>Alice</Username>
    <Password>qwerty123</Password>
  </User>
  <User>
    <Username>Bob</Username>
    <Password>   </Password>
  </User>
</UserList>

My proposal will not lose data for ANY data-oriented (i.e.
non-mixed-content) XML file. Your proposal would not lose data for 99.9% of
these XML files, but that .1% is a killer. Especially since sometimes (e.g.
in the second example above), it'll work fine until you hit an edge case, so
QA may not find the problem. Not that this second example is a good idea,
but you get the picture.

It's true that my proposal will leave unnecessary whitespace in certain
cases, like empty lists, but that shouldn't really cause an actual problem,
should it?
