The link goes to the issuing authority’s own document — the one we read to produce this record. Where a source publishes whole titles rather than sections, your browser may need a moment to jump to the provision.
Unofficial copy of government-published law, reproduced from official sources with full provenance. Not an official publication; verify against official sources before relying on it in a filing. Records in the 'guidance' corpus, and only that corpus, are sub-regulatory (interpretive guidelines, survey procedures) and are not binding law. Validity bounds follow each jurisdiction's declared temporalBasis.
