-- Generic Percentage type

Percentage ::= INTEGER (1..100)

-- Generic percentage value

-- 1 to 100 = percentage (e.g., 68%, 95%, 99%)

-- Updated UncertaintyMeters positive integer with no cap

UncertaintyMeters ::= INTEGER (1..MAX)

-- Uncertainty/error estimate in meters

-- 1 to MAX = estimated error radius in meters

-- WGS84Altitude (unchanged from original CR)

WGS84Altitude ::= INTEGER (-1000..50000)

-- Altitude in meters above WGS84 ellipsoid

-- Range: -1000m (below sea level) to 50000m (stratosphere)

UncertaintyMeters ::= INTEGER (1..10000)

-- Uncertainty/error estimate in meters

-- 1-9999 = estimated error radius in meters

-- 10000 = unknown/unspecified uncertainty
