4.8.7 Start a Segment
The segment command can be used to start a segment of HTML within a Markdown field.
A segment is genereally intended to be something like a div or an aside, but can be any HTML element.
The intended element name follows the command, as in the following example.
{:segment: aside}
A segment command should always be followed at some later point by an endssegment command.
Note that a class value and/or an id value can also be specified, in that sequence, using pipes to separate the parameters.
Also note that segment commands may be nested, if the resulting HTML would be valid.
