The final file that you create should look like rather similar to the following:
<?xml version="1.0" encoding="UTF-8"?>
<text>
<s><cl>In the first chapter
we <vb>find out</vb>about many things.</cl></s>
<s>For example that there <vb>are </vb> different kinds of process types.</cl></s>
<s>In the second chapter we <vb>find out </vb> more of the same kind
of thing, </cl><cl>but in much more detail.</cl></s>
<s><cl>That not only <vb>are</vb> there many different types of processes, </cl>
<cl>but that these also <vb>come</vb>
with different kinds of participants</cl></s>
</text>
This is also available as an xml file here.
