## Description

A `Step` identifies a unit of action in a `Procedure`. If a finer level of granularity is required for some steps, you can embed `SubSteps` in a `Step`. Embedded `SubSteps` contain `Step`s, so that substeps can be nested to any depth.

### Processing expectations

Formatted as a displayed block. `Step`s are almost always numbered.

### Parents

These elements contain step: `procedure`, `substeps`.

### Children

The following elements occur in step: `abstract`, `address`, `anchor`, `authorblurb`, `beginpage`, `blockquote`, `bridgehead`, `calloutlist`, `caution`, `classsynopsis`, `cmdsynopsis`, `constraintdef`, `constructorsynopsis`, `destructorsynopsis`, `epigraph`, `equation`, `example`, `fieldsynopsis`, `figure`, `formalpara`, `funcsynopsis`, `glosslist`, `graphic`, `graphicco`, `highlights`, `important`, `indexterm`, `informalequation`, `informalexample`, `informalfigure`, `informaltable`, `itemizedlist`, `literallayout`, `mediaobject`, `mediaobjectco`, `methodsynopsis`, `msgset`, `note`, `orderedlist`, `para`, `procedure`, `productionset`, `programlisting`, `programlistingco`, `qandaset`, `remark`, `screen`, `screenco`, `screenshot`, `segmentedlist`, `sidebar`, `simpara`, `simplelist`, `substeps`, `synopsis`, `table`, `tip`, `title`, `variablelist`, `warning`.

## Attributes

performance

  `Performance` specifies whether particular `Step` in a `Procedure` must be performed or is optional.

## Examples

For examples, see `procedure` .
