Tag Name	Description
Head1	This is the major header tag and is used for chapter titles.
Head2	This is the mid-level header tag used for section headings.
Head3	This is the next level header used for subsection headings.
Head3A	This is the same as Head3 but indents the paragraph further in the table of contents.
Head4, Head5	These are used for lower level headings, for example, example headings.
Body Text	This is the default tag for any paragraph which is not otherwise tagged.
Fixed Text	This tag is used for paragraphs which should not be formatted by the DOSBook display program. Its primary use is for computer input/output messages.
Bullet	When points are being listed, it is useful to place a bullet at the start of each block of text and have the text indented. This tag is used for that purpose. Text is indented after the bullet in the same way as the Indent tag.
Indent	Indents text from the left without a bullet.
Pre-Indent	Outdents text to the left. The compiler expects an Indent tag to follow a Pre-Indent.
Table Header	Provides a heading for tables which have titles.
Table Desc	Provides a subsidiary header for a table, with head text above each column. This tag separates text which contains a Tab into two parts, one over each column in a table.
Table Item	Use this tag for text in a table, and separate columns of text using the tabs if necessary.
Prompt	Some fixed text has a special format: a specific drive letter followed by a command. The two tags Prompt and Command allow for this. Text in a prompt paragraph is not terminated by a new line and the compiler expects a Command paragraph to follow it.
Command	Formats text in a command, indenting it to the left.
New Page	Forces a new page. No text should be present in such a paragraph. These are ignored by the DOSBook display program but allow the user to split text between pages to make the text easier to read.
Line Under	This tag results in a line being drawn across the width of the screen. There should not be any text associated with this tag. Use this tag after the last line of text in a table, for example.
