Overview

Validates values against XSD totalDigits facet

The totalDigits facet specifies the maximum number of digits (excluding leading zeros, trailing zeros after decimal point, and decimal point itself) for decimal and integer types.

Examples:

Validating total digits

facet = Lutaml::Xsd::TotalDigits.new(value: "5")
validator = TotalDigitsFacetValidator.new(facet)
validator.valid?("12345")    # => true (5 digits)
validator.valid?("123.45")   # => true (5 digits)
validator.valid?("123456")   # => false (6 digits)
validator.error_message("123456")
# => "Value has 6 digits, exceeds maximum of 5 total digits"
