A mapplet can't be used in another mapplet.Because if you try to drag and drop one mapplet from the left hand side under the mapplet subfolder to the mapplet designer workspace it won't allow you to do so, but if you try to drag and drop one mapplet to one mapping,i.e., in the mapping designer then it comes to the workspce.This means a mapplet can only be used in a mapping but can't be used in another mapplet.That's why mapplet is known as the reusable form of mapping.

RE: Mapplet Transformations

A mapplet can't be used in another mapplet .Because if you try to drag and drop a mapplet from the left hand side of the Mapplet subfolder to the mapplet designer workspace it won't allow you to do so. But if you try to drag and drop a mapplet to a mapping in the mapping designer its only possible.It clearly indicates that a mapplet is created using the mapplet designer and it only can be used in a mapping not in another mapplet.That's why mapplet is known as the reusable form of a mapping.
