What the registry records
The registry records formal institutional entries that require identifiable public reference.
These may include authorization-related entries, status notes, institutional records,
and other materials that depend on traceable standing.
Registry is not intended to absorb every published page.
It records what must be distinguishable in institutional status or effect.
Document identifiers
Document identifiers exist so that public institutional materials
can be referenced without confusion.
An identifiable entry is easier to review, compare, correct,
or supersede than an undefined publication.
Identifiers support orderly record,
especially when authorization, revision, or status questions arise.
