As you can see header fields are used to tag _all_ allowed extensions. The extensions that are common are automatically activated.

header fields are build up as the following:

&lt;name&gt; : &lt;content&gt;
&lt;name&gt; = &lt;string&gt;
&lt;content&gt; = &lt;string [,&lt;string&gt;...]
&lt;string&gt; = array of characters not containing special characters like \r\n : , etc.

This allows for shorter headers as version numbers can be put on 1 line
