Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Introduction
ISO 32000-2 introduced the mechanism for defining namespaces within a logically structured PDF
document; identified two recognized namespaces for tagged PDF documents; and provided strict
hierarchical inclusion rules for the standard structure namespace for PDF 2.0. However, ISO 32000-2
did not specify restrictions and inclusion rules for the standard structure namespace for PDF 1.7. This
document extends the hierarchical inclusion rules to address both the standard structure namespace
for PDF 2.0 and the standard structure namespace for PDF 1.7.
The primary purpose of this document is to extend the rules already defined within ISO 32000-2 to
resolve any ambiguity.

TECHNICAL SPECIFICATION ISO/TS 32005:2023(E)
Document management — Portable Document Format
— PDF 1.7 and 2.0 structure namespace inclusion in ISO
32000-2
1 Scope
This document specifies containment requirements for tagged PDF documents that use the PDF 1.7
namespace and the PDF 2.0 namespace. These containment requirements extend, and entirely comply
with, the rules and provisions already specified for tagged PDF documents within ISO 32000-2.

4 Declaration of conformance
This document defines additional requirements that are fully compliant with ISO 32000-2. As such, a
PDF document can conform to all the requirements of ISO 32000-2 and the requirements defined in this
document, retaining compliance with both standards. However, not all files which are compliant with
ISO 32000-2 will be compliant with this document.
To enable interchange and to identify that a given PDF document conforms to the requirements defined
in this document, that PDF document may include a PDF declaration of conformance with this document.
When such a PDF declaration is present, it shall conform to the requirements of the PDF Declarations
specification. Such claim of conformance shall take the form described in Table 1.
