DEPL — Missing explanation for selectRequirement in SubcomponentInstantiationDescr

The diagram for the SubcomponentInstantiationDescription shows
a composition relationship to Requirement called selectRequirement
that is not mentioned in the class' Associations section.

Proposed resolution:

In section 3.4, "Component Data Model", in the description of the
SubcomponentInstantiationDescription class, add the following text
to the "Associations":

selectRequirement: Requirement [*]
Expresses selection requirements on the implementation that
will be chosen for the subcomponent. During planning, these
selection requirements are matched against implementation
capabilities in the ComponentImplementationDescription elements
that are part of the referenced package
