The schema does not enforce those aggregate limits, Unicode scalar validity or calendar semantics by itself. Use the SDK conformance validator. The source pattern is a conservative absolute HTTPS/URN URI subset. UTC timestamps allow seconds 00-59 and 1-3 fractional digits; no leap seconds. All time formats must be actively asserted by external validators.",
