+ <p>This processor takes in a record set and counts both the overall count and counts that are defined as dynamic properties
+ that map a property name to a record path. Record path counts are provided at two levels:</p>
+ <ul>
+ <li>The overall count of all records that successfully evaluated a record path.</li>
+ <li>A breakdown of counts of unique values that matched the record path operation.</li>
+ </ul>
+ <p>Consider the following record structure:</p>
+ <pre>
+ {
+ "sport": "Soccer",
+ "name": "John Smith"
+ }
+ </pre>
+ <p>A valid mapping here would be <em>sport => /sport</em>.</p>
+ <p>For a record set with JSON like that, five entries and 3 instances of soccer and two instances of football, it would set the following
+ attributes:</p>
+ <ul>
+ <li>record_count: 5</li>
+ <li>sport: 5</li>
+ <li>sport.Soccer: 3</li>
+ <li>sport.Football: 2</li>
