rdml-qpcr 0.1.1

//! Completeness pin: every element and attribute declared in the 1.4 XSD
//! must appear in the kitchen-sink fixture's emitted output.
//!
//! Together with the `xsd_validation` test (libxml2 enforces `xs:sequence`
//! order on those same elements) this pins the writer's element order
//! against the schema: an element the writer forgot, misnamed, or emitted
//! in the wrong place fails one of the two tests.
