Detailed Description

Data structure that captures multiple levels of template argument lists for use in template instantiation.

Multiple levels of template arguments occur when instantiating the definitions of member templates. For example:

 template<typename T>
 struct X {
   template<T Value>
   struct Y {
     void f();
   };
 };

When instantiating X<int>::Y<17>::f, the multi-level template argument list will contain a template argument list (int) at depth 0 and a template argument list (17) at depth 1.
