OptionalAuthorOptionalcrsOptionalBounds?: CrsPlausibilityBoundsEnables the transposition check (§9.1). Without it there is no test.
OptionalDescription?: stringOptionalGeodeticDatum?: stringOptionalMapProjection?: stringOptionalMapZone?: stringOptionalVerticalDatum?: stringOptionalimageryImagery the caller will texture on the TIN (§15.5), recorded as
provenance in LandXML_Conversion. The texture is not written here: the
appearance workspace's planner writes it on surfaceElements.
OptionalOrganizationOptionalsourceRecorded as provenance (§7); never used to decide anything.
OptionalsourceOptionalswapOperator-confirmed northing/easting swap for a known-faulty producer (§2.2 item 2). Recorded as provenance, exactly like the units override.
OptionaltimestampFixed epoch-ms, for byte-deterministic output.
