Content Pipeline Document Object Model
The XNA Game Studio Content Document Object Model (DOM) represents the set of built-in classes that can be consumed by standard content processors.
Currently, the DOM provides support for meshes, materials, textures, sprite-fonts, and animations. Outside of these, a custom importer can return a ContentItem with custom information in its opaque data, or a custom type you have developed.
The following diagram lists the complete Content DOM.
