syntaxdiagram

The syntax diagram (<syntaxdiagram>) element is the main container for all the syntax elements that make up a syntax definition. The syntax diagram represents the syntax of a statement from a computer language, or a command, function call or programming language statement. Traditionally, the syntax diagram is formatted with "railroad tracks" that connect the units of the syntax together, but this presentation may differ depending on the output media. The syntax diagram element is part of the DITA programming domain, a special set of DITA elements designed to document programming tasks, concepts and reference information.

Example

<syntaxdiagram>
 <title>CopyFile</title>
 <groupseq><kwd>COPYF</kwd></groupseq>
 <groupcomp><var>input-filename</var><kwd>*INFILE</kwd></groupcomp>
 <groupseq><var>output-filename</var><kwd>*OUTFILE</kwd></groupseq>
 <groupchoice> <var>input-filename</var> <kwd>*INFILE</kwd></groupchoice>
 <groupchoice> <var>output-filename</var> <kwd>*OUTFILE</kwd></groupchoice>
</syntaxdiagram>
