the same layout object as the immediately preceding basic logical object. No other
expression is allowed.
11 Fascicle VII.7 - Rec. T.502
6.3 Layout structure
6.3.1The generic layout structures
A 'complete' and a 'partial' generic layout structure are defined in this document
application profile. The 'complete' generic layout structure is present in processable
and formatted processable documents and defines all possible specific layout structures
that may be created as a result of the document layout process.
The 'partial' generic layout structure may only be used in formatted form documents.
It is used only to provide predefined attribute values and content portions for layout
objects in the specific layout structure (i.e. factorization).
6.3.1.1 The 'complete' generic layout structure
A general description of the permissible document layout structure is given in
5.3.1. In order to represent these structures, the generic layout structure consists of
four hierarchical levels, each of which must always be present:
- the document layout root;
- the page set level (one level only);
- the page level;
- the frame level (one level only).
The document layout root consists of one or more subordinate page sets, where the
number of page sets is unrestricted. Each page set may consist of a sequence of one or
more subordinate pages in accordance with the specification given in 5.3.1.
Each of these pages may contain one, two or three subordinate frames that are used
to represent the header, body and footer area as described in 5.3.2. The body area
frame is mandatory, whereas the header and footer frames are optional. These frames any
or may not be adjacent to one another but they must not overlap.
The layout path is always 270 degrees for each frame and it is not possible to alter
this value. The attribute "medium type" specifies the size of the nominal page
corresponding to each layout object of the type page and specifies whether the nominal
page is to be in portrait or landscape orientation.
Content in the specific logical structure is laid out in the body frames; this
content cannot be laid out in the header or footer frames. The header and footer frames,
if present, must contain the attribute "logical source" which indicates the appropriate
generic logical object class that contains the content to be laid out in those frames.
The 'complete' generic layout structure may vary in accordance with the layout
requirements of each particular document. In a particular 'complete' generic layout
structure, the value of the attribute "generator for subordinates" in the document layout
root, in each page set and in each page define the allowable specific layout structures
for that particular document. The ranges of all possible values of the attribute
"generator for subordinates" at each of the hierarchical levels in the 'complete' generic
layout structure are defined formally in 6.3.3.2.1.
This definition, in effect, defines all possible generic layout structures that are
allowed by PM1. These structures are illustrated in Figures 8/T.502 and 9/T.502. Figure
9/T.502 shows the five ways in which pages within a page set can be specified, in
accordance with 5.3.1.
Fascicle VII.7 - Rec. T.502 12
FIGURE 8/T.502
Example of a particular generic layout structure
FIGURE 9/T.502
Illustration of the possible page set classes
6.3.1.2 The 'partial' generic layout structure
The 'partial' generic layout structure may consist of the following object classes:
- the document layout root class;
- page set classes;
- page classes;
- frame classes.
All these classes are optional; each type of class may occur one or more times
within a particular document, except the document layout root class, which may only occur
one. The document layout root, each page set class and each page class may or may not
reference other object classes in the 'partial' generic layout structure by means of the
attribute "generator for subordinates".
13 Fascicle VII.7 - Rec. T.502
6.3.2The specific layout structure
In the case of a formatted processable document, the specific layout structure
present in a document must comply with the particular generic layout structure present in
that document.
In the case of formatted documents, no 'complete' generic layout structure is
present but the specific structure must comply with an allowable 'complete' generic
layout structure, as defined in 6.3.2.1. If a 'partial' generic layout structure is
present, then the objects in the specific layout structure may or may not refer to
objects in that generic layout structure.
The following additional restrictions are also applicable to the specific layout
structure:
- each frame must contain one or more subordinate blocks;
- each block must reference only one content portion.
