Adding application config file to web.config - iis-7

Question

I am running IIS7.
I have a 3rd party dll that has its own config file. My understanding is that IIS7 will not read this config file and that I have to add it to the server web.config file.
However I get errors when adding a particular node.
In the dll.config it has:
<configuration>
<dllSettings>
--- bunch of settings....
</dllSettings>
</configuration>
So I added that same node into my web.config file...
Is there a parent node that I should add this to in my web.config?

When I have to add more config file. This is how I defined in the Web.Config
<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">
<configSections>
<sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
<section name="[NAMESPACE].[PROJECT].Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false"/>
</sectionGroup>
</configSections>
<applicationSettings>
<[NAMESPACE].[PROJECT].Properties.Settings configSource="[NAMESPACE].[PROJECT].dll.settings.config"/>
</applicationSettings>
...
</configuration>
This is what I have in my other Config File
<?xml version="1.0" encoding="utf-8" ?>
<[PROJECT].Properties.Settings>
<setting name="[NAME]" serializeAs="String">
<value>Anything</value>
</setting>
</[PROJECT].Properties.Settings>
