if you code anything, it is better to avoid redundancy. it makes no
sense to double information/functions that are already written at
another place.

we should strive for the goal to simplify things, not to complicate them.
yes, there is some reduncy in xml, like in start and end tags, and yes,
it is to make code more human readable. xml could have been defined as
the following without loosing functionality:

    <child>content 1</>
    <child>content 2</>

find your own approach to structure your documents by intending and
commenting, as the other posters said.

i for example use vi as an editor, indent my code and use vi's manual
folding-capabilities through comments. e.g.:

<!-- {{{ navigation -->
<div class="nav_main">
        <li>point 1</li>
        <li>point 2</li>
<!-- }}} -->
<!-- {{{ content -->
<div class="content">
    <h1>headline 1</h1>
<!-- }}} -->

but that depends on your editor and the team you are working with.
