const SCHEMA_VERSION: 1;ariana-report template model.
A template is a plain JSON document. All positions and sizes are expressed in
the template’s unit, except font sizes which are always in points.
Layout is banded:
- page-level bands: reportHeader, pageHeader, pageFooter, reportFooter
- body: a sequence of static bands and data regions
- a data region iterates rows of a JSON data source and has an optional header, groups (each with header/footer), a detail band, a footer and nested child regions (master-detail).
