UPDMRTF — pacakge partitioning not clear

According to the explanation, the “Partitioning” is the package. However, I couldn’t find the packaged diagrams except for the “Aliases”. It seems that it is necessary to define UPDM using Package diagrams.

Replace the Pertitioning section 7.3 with the following.
Partitioning: The UPDM profile is organized as a number of hierarchical packages that are used to group elements, and to provide a namespace for those grouped elements. The top level structure of these packages can be seen in Figure 2.2.(Packages are represented in the diagram by a rectangle with a tab in the upper left hand corner).
