[xsd-users] Deleting empty elements

This is the same source example you gave me before, but this will only
remove the empty tags, not the tags that become empty *after* you delete all
the empty tags.

For example, with

<a>
    </b>
</a>

Only the tag </b> is empty, so only it will get deleted by your functions.
However, after it gets deleted, you are left with

<a>
</a>

so *now* there is another empty tag, hence my iteration over the entire set
until no more changes are visible.
