The category of DynamicContent is a top-level classification in the ControllerTaxonomy.
Most current web frameworks fall into this category. Returning a document in response to an HTTP request is still the focal point. The document sent back is generated on the fly, though, and various ways are used to invoke other code in the process.
The category of dynamic content is divided into those with MixedConcerns and those with SeparatedConcerns.
