Level

Level references a formal level defined within the hierarchy which defines this hierarchical code. This is only necessary if the nesting depth of the hierarchical code does not correspond to the nesting depth of the level to which it belongs (i.e. the hierarchical code is to skip down a level). Otherwise, the code is assumed to exist at the level in which the nesting depth of the level matches the nesting depth of the code.
