All report fields: some Segment fields shown as Attribute fields?

[hiromi hishida]

Hi.

I recently read through the "All reports" document: https://developers.google.com/adwords/api/docs/appendix/reports/all-reports, and  found some strange "Attributes".

For example,
- CampaignId in SEARCH_QUERY_PERFORMANCE_REPORT
- CampaignId in GEO_PERFORMANCE_REPORT
- MostSpecificCriteriaId, CityCriteriaId, MetroCriteriaId, RegionCriteriaId in GEO_PERFORMANCE_REPORT

I suppose they are not "Attribute", they are "Segment".

I did several experiments to confirm them.
- SEARCH_QUERY_PERFORMANCE_REPORT without CampaignId shows reports grouped only by queries successfully.
- GEO_PERFORMANCE_REPORT without CampaignId shows reports grouped only by areas successfully.
- GEO_PERFORMANCE_REPORT only with CountryCriteriaId show reports grouped only by countries(not regions, metros, cities, most specific areas) successfully.

So I think the document is wrong, they are "Segment" (not "Attribute").
Is it correct?
