Standard-role and attribute relations; layout, word breaks and intended reading order remain explicit.

UserProperties

Ordered properties; their presence requires MarkInfo.UserProperties=true (page 577).

UserProperty

A user property is data, with an explicit display representation and visibility (page 577).

VersionedComponent

A native mechanism validates the versions of its actual selected features.

NameTreeChildren

A nonempty, ordered Kids collection (PDF32000_2008.pdf, 7.9.6, PDF page 97).

NameTreeEntry

NumberTree

A sorted number-tree leaf or branch (ISO 32000-1, 7.9.7).

NumberTreeChildren

A nonempty, ordered Kids collection (PDF32000_2008.pdf, 7.9.7, PDF page 99).

NumberTreeEntry

PDFDocEncodedString

PdfDateValidation

PDF date values only: ISO_32000-2_sponsored_EC3.pdf,7.9.4, physical pp.133–134.

PdfDocOrUtf16TextStringEncoding

Unambiguous PDFDocEncoding or UTF-16BE (ISO_32000-2_sponsored_EC3.pdf, PDF pp. 131–132).

Rectangle

Four coordinates; reversed corners remain legal (ISO 32000-1, 7.9.5).

TextString

Immutable application text with an explicit encoding object (ISO_32000-2_sponsored_EC3.pdf, 7.9.2.2.1, PDF pp. 131–132).

TextStringDecoder

Version-scoped BOM interpretation (ISO_32000-2_sponsored_EC3.pdf, 7.9.2.2.1, PDF pp. 131–132).
