Formatter - always the same format?

Just tried the different formatters in latest Cobalt release. Added all available formatter URL parameters... and it always begins with:

# This is INI formated article list of section ... 

Then there are some text blocks for all records with:

[record 22] ... 

Obviously followed by the records definition in XML format

<?xml version="1.0" encoding="UTF-8"?>

<section>

    <title>Profiles Title</title>

    <records>

                <record>

            <id>22</id> ... 

Questions:

• Why does it begin with INI. End then there is XML ?
• Why do ALL formatter options show the same content and format ?
