expeDITA Shortcodes
Popular blogs provide authors with a set of pseudo-markup called shortcodes that represent special function during the rendering of the page.
XML markup sometimes directly supports semantic features such as messages. Other special behaviors can be associated to markup by values used in the outputclass attribute when the issue is simply switching the processing for a particular structure such as definition lists being rendered as a table instead of as a list.
linebreak (carriage return effect)
<?xpd-html linebreak?>
Function: for HTML renderings only, this processing instruction inserts an HTML line break element (<br/>).
<navtitle>Solutions: <?xpd-html linebreak?>subhead</navtitle>
Result: This line has a linebreak
after the word "linebreak".
