Can a Report ID be reused in multiple Application Collections?

[NZSmartie]

For now, I'm going with the assumption that, although a Report ID can be reused, can not be reused in a sibling application collection due to complexity.

Edit: Going to allow this, turns out to be easier to implement if it is assumed that Report IDs can be reused in multiple application collections

HID Spec v1.11

6.2.2.7 Global Items

Remarks:
...

• The same Report ID value can be encountered more than once in a report
  descriptor. Subsequently declared Input, Output, or Feature main items will be
  found in the respective ID/Type (Input, Output, or Feature) report.

8.3 Report Constraints

Each top level collection must be an application collection and reports may not
span more than one top level collection
