.net - Configuration section with sub element and variable attributes -

Is it possible to implement such a structure? NET configuration class:

  & lt; MyFramework myAttr1 = "myValue1" myAttr2 = "myValue2" ... & gt; & Lt; Hosting class = "My.Framework.Hosting1" hosting 1Attr1 = "value" hosting1Attr2 = "value" /> & Lt; / MyFramework & gt;  

Hosting class may be different, and therefore may vary with the necessary attributes, i.e. someone else is having a different hosting Element:

  & lt; Hosting class = "My.Framework.Hosting2" hosting 2Only1Attr = "value" />  

What is the correct way to implement it? I have only seen the concepts of a provider model, however, it seems that the provider can enable the user to configure multiple hosting elements !!
