+ <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>

These property names should be more self-descriptive and not to overlap
other property name spaces.
I suggest following names:
|current|suggestion|
|-------|------------|
|record_count|recordStats.count|
|sport|recordStats.sport.count|
|sport.Soccer|recordStats.sport.count.Soccer|
|sport.Football|recordStats.sport.count.Football|
Then we can add more stats later, such as recordStats.age.min or
recordStats.age.max ... etc
