*:* Any element from any namespace except the DocBook namespace
The arch attribute designates the computer or chip architecture to which the element applies. The condition attribute provides a standard place for application-specific effectivity. Many DocBook users observed that in order to add an effectivity condition that was unique to their environment required abusing the semantics of one of the existing attributes, or adding their own, making their customization an extension rather than a subset . Thecondition attribute is a general-purpose effectivity attribute with no specified semantics. The conformance attribute indicates standards conformance characteristics of the item contained in the element. These characteristics are application-specific; DocBook provides no default semantics. The os attribute indicates the operating system to which the element is applicable. The revision attribute indicates the editorial revision to which the element belongs. The security attribute indicates something about the security level associated with the element to which it applies. The userlevel attribute indicates the level of user experience to which element applies. The vendor attribute indicates the computer vendor to which the element applies. The wordsize attribute indicates the word size (width in bits) of the computer architecture to which the element applies. simple new replace embed other onLoad onRequest other none changed added deleted off continues restarts numbered unnumbered preserve compact normal 0 1 If pgwide has the value 0 (false), then the element is rendered in the current text flow (with flow column width). A value of 1 (true) specifies that the element should be rendered across the full text page. optional required center char justify left right bottom middle top doi isbn isrn issn libraryofcongress pubnumber uri The class identifies the kind of bibliographic identifier: Value Identifier doi A Digital Object Identifier . isbn An International Standard Book Number . isrn An International Standard Technical Report Number as defined by ISO 10444:1994. issn An International Standard Serial Number . libraryofcongress A Library of Congress subject identifer pubnumber A publication number, for example from a private or corporate numbering scheme. uri A Uniform Resource Identifier. other Some other kind of identifier.

link A hypertext link The link element is a general purpose hypertext element. Usually, link surrounds the text that should be made “hot” (unlike xref which must generate the text) but the endterm attribute can be used to copy text from another element. If the link element has content, then that content is processed for output as the “hot” text. If the link element has content and an endterm attribute, then the content is used and the endterm is ignored. If the link element has an endterm attribute and no content, then the content of the element pointed to by endterm should be repeated at the location of the link and used as the “hot” text.

Identifies the editorial or publication status of the element on which it occurs Publication status might be used to control formatting (for example, printing a “draft” watermark on drafts) or processing (perhaps a document with a status of “final” should not include any components that are not final). Specifies an identifying string for presentation purposes Generally, an explicit Label attribute is used only if the processing system is incapable of generating the label automatically. Under such circumstances, the third book in a set might be labeled “Volume III”, for example. If present, the label is normative; it will used even if the processing system is capable of automatic labelling.

The body may include a table of contents and multiple lists of tables, figures, and so on, before the main text of the article and may include a number of common end-matter components at the end. Formatted as a displayed block. Frequently causes a forced page break in print media. May be numbered separately and presented in the table of contents.

The frame specifies how the table is to be framed: Value Meaning all Frame all four sides of the table. In some environments with limited control over table border formatting, such as HTML, this may imply additional borders. bottom Frame only the bottom of the table. none Place no border on the table. In some environments with limited control over table border formatting, such as HTML, this may disable other borders aswell. sides Frame the left and right sides of the table. top Frame the top of the table. topbot Frame the top and bottom of the table. There is no way to obtain a border on only the starting edge (left, in left-to-right writing systems) of the table. all bottom none sides top topbot If colsep has the value 1 (true), then a rule will be drawn to the right of all columns in this table. A value of 0 (false) suppresses the rule. The rule to the right of the last column in the table is controlled by the frame attribute, not colsep . If rowsep has the value 1 (true), then a rule will be drawn below all rows in this table. A value of 0 (false) suppresses the rule.
