                         <p>A <code>part</code> provides for logical partitioning of prose, and can be thought of as a grouping structure (e.g., section). A <code>part</code> can have child parts allowing for arbitrary nesting of prose content (e.g., statement hierarchy). A <code>part</code> can contain <code>prop</code> objects that allow for enriching prose text with structured name/value information.</p>
                         <p>A <code>part</code> can be assigned an optional <code>id</code>, which allows for internal and external references to the textual concept contained within a <code>part</code>. A <code>id</code> provides a means for an OSCAL profile, or a higher layer OSCAL model to reference a specific part within a <code>catalog</code>. For example, an <code>id</code> can be used to reference or to make modifications to a control statement in a profile.</p>
