Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for
to be
which a technical committee has been established has the right
represented on that committee. International organizations, governmental
and non-governmental, in liaison with 1.30, also take part in the work. IS0
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for approval before their acceptance as
International Standards by the IS0 Council. They are approved in ac-
cordance with IS0 procedures requiring at least 75% approval by the
member bodies voting.
International Standard IS0 9070 was prepared by Technical Committee
lSO/TC 97, information processing systems.
Annexes A and B of this International Standard are for information only.

Introduction
This International Standard has been developed to support the use of the
Standard Generalized Markup Language (SGML), defined in IS0 8879.
IS0 8879 allows the sharing of “public text”, which it defines as:
Text that is known beyond the context of a single document or system
environment, and which can be accessed with a public identifier.
A public identifier identifies both the owner of the text, and the text itself.
Construction of public identifiers is largely left to owners of the public text
to be identified. Some minimal procedures are required to avoid the
chance of two owners assigning the same identifiers to different items.
This International Standard defines such procedures, based upon the al-
location of unique identifier prefixes to each owner which are incorporated
into registered owner identifiers.
NOTE 1 The existence of an item of public text does not imply that it is readily
available to all users. It may be “public” only within an organization, and may have
a registered owner identifier solely to avoid conflict with the identifiers of other
public text.
