#### 38.1.1 Understanding DITA2Go PI marker syntax

In DITA2Go a DITA processing instruction is called a PI marker. A PI marker has the form:

    <?dtxxx markertype="markervalue" markertype2="markervalue2" ... ?>

where:

xxx | designates the output type
markertype | names the type of instruction or value
markervalue | is the actual instruction or value.

You can include multiple key="value" pseudo-attributes or tokens in the same PI marker, separated by spaces. For example:

    <?dthtm GraphWidth="80" GraphHeight="100" ?>

This PI syntax is supported by all XML editors, and is easily extended to specify any instruction.

DITA2Go PI markers include the following output types:

dthtm | all HTML/XML outputs
dtrtf | Word output
dtpdf | print outputs, including such as DocBook dbfo
dtall | all outputs
