This is generated reference documentation for all user-specifiable processing instructions (PIs) in the “common” part of the DocBook XSL stylesheets. You add these PIs at particular points in a document to cause specific “exceptions” to formatting/output behavior. To make global changes in formatting/output behavior across an entire document, it’s better to do it by setting an appropriate stylesheet parameter (if there is one). dbchoice_choice Generates a localized choice separator dbchoice choice="and"|"or"|string" Use the dbchoice choice PI to generate an appropriate localized “choice” separator (for example, and or or) before the final item in an inline simplelist This PI is a less-than-ideal hack; support for it may disappear in the future (particularly if and when a more appropriate means for marking up "choice" lists becomes available in DocBook). choice="and" generates a localized and separator choice="or" generates a localized or separator choice="string" generates a literal string separator dbtimestamp Inserts a date timestamp dbtimestamp format="formatstring" [padding="0"|"1"] Use the dbtimestamp PI at any point in a source document to cause a date timestamp (a formatted string representing the current date and time) to be inserted in output of the document. format="formatstring" Specifies format in which the date and time are output For details of the content of the format string, see Date and time. padding="0"|"1" Specifies padding behavior; if non-zero, padding is is added dbtex_delims Generates delimiters around embedded TeX equations in output dbtex delims="no"|"yes" Use the dbtex delims PI as a child of a textobject containing embedded TeX markup, to cause that markup to be surrounded by $ delimiter characters in output. This feature is useful for print/PDF output only if you use the obsolete and now unsupported PassiveTeX XSL-FO engine. dbtex delims="no"|"yes" Specifies whether delimiters are output tex.math.delims
