One per-class behavior rule (classBehavior in the section options): class name(s) —
category form ('flow') or IFC form ('IfcPipeSegment'), matched case-insensitively —
plus what the matched products do in the section. Declared here rather than in
product-geometry (where the matcher lives) so that packages which cannot depend on
product-geometry — printing templates carry these rules — share the one type.
