### Formal Views of Profile Content

 [Description of Profiles, Differentials, Snapshots and how the different presentations work](http://build.fhir.org/ig/FHIR/ig-guidance/readingIgs.html#structure-definitions).

### Notes:

#### Section Modeling Variants

The profile allows both section modeling variants:

1. Top-level section(s) with direct`entry`elements (no sub-sections)
1. Top-level section(s) that contain nested sub-sections

Example with sub-sections:

* [BundleLabResultMicroCultureSusc](Bundle-BundleLabResultMicroCultureSusc.md)

Example without sub-sections:

* [BundleHepatitisPanel](Bundle-BundleHepatitisPanel.md)
