            CHAPTER 10                                                        Document Interchange



STRUCTURE TYPE     DESCRIPTION

Quote              (Quotation) An inline portion of text attributed to someone other than the author of the
                   surrounding text.
                   Note: The quoted text is contained inline within a single paragraph. This differs from the
                   block-level element BlockQuote (see “Grouping Elements” on page 899), which consists of one
                   or more complete paragraphs (or other elements presented as if they were complete para-
                   graphs).

Note               (Note) An item of explanatory text, such as a footnote or an endnote, that is referred to
                   from within the body of the document. It may have a label (structure type Lbl; see “List El-
                   ements” on page 902) as a child. The note may be included as a child of the structure ele-
                   ment in the body text that refers to it, or it may be included elsewhere (such as in an
                   endnotes section) and accessed by means of a reference (structure type Reference; see be-
                   low).
                   Note: Tagged PDF does not prescribe the placement of footnotes in the page content order.
                   They can be either inline or at the end of the page, at the discretion of the producer applica-
                   tion.

Reference          (Reference) A citation to content elsewhere in the document.

BibEntry           (Bibliography entry) A reference identifying the external source of some cited content. It
                   may contain a label (structure type Lbl; see “List Elements” on page 902) as a child.
                   Note: Although a bibliography entry is likely to include component parts identifying the cited
                   content’s author, work, publisher, and so forth, no standard structure types are defined at this
                   level of detail at the time of publication.

Code               (Code) A fragment of computer program text.

Link               (Link) An association between a portion of the ILSE’s content and a corresponding link
                   annotation or annotations (see “Link Annotations” on page 622). Its children are one or
                   more content items or child ILSEs and one or more object references (see “PDF Objects as
                   Content Items” on page 868) identifying the associated link annotations. See “Link Ele-
                   ments,” below, for further discussion.

Annot              (Annotation; PDF 1.5) An association between a portion of the ILSE’s content and a corre-
                   sponding PDF annotation (see Section 8.4, “Annotations”). Annot is used for all PDF an-
                   notations except link annotations (see the Link element, above) and widget annotations
                   (see the Form element in Table 10.27 on page 912). See “Annotation Elements” on page 909
                   for further discussion.
