MARTE — concept of "resource"

The General Resource Model of MARTE seems to define the concept of "resource" both at the instance and classifier levels. For instance, the GRM::Resource stereotype extends both InstanceSpecification and Classifier.

The SwResource stereotype defined in the Software Resource Model of MARTE specializes the GRM::Resource stereotype. However, reading the SRM chapter, it seems that its use is much more focused on description of classifiers (to characterize properties or behavioral features for instance) than instances.

In that context, does it make sense to apply a SRM::SwResource stereotype or one of its subclasses (for instance SRM::SwSchedulableResource) on an instance specification? Note that it seems to be legal given that SRM::SwResource specializes GRM::Resource, which extends InstanceSpecification.

I would be pretty handy to do so, in order to describe a resource platform model provided in input of a scheduling analysis.

Complete the paragraph 7.3 with the rules for the default values of attributes of the stereotypes for instance of classifiers also stereotyped.
