<overview>
<p>This query finds namespaces that have an abstractness greater than 0.20.</p>

<p>Abstractness measures the proportion of abstract types in
      a package relative to the total number of types in that package.
      A metric value close to 1 indicates a highly abstract package
      that is also unstable. The class hierarchy is probably over-engineered, and the abstract types are unlikely to be much used.</p>
</overview>

<recommendation>
<p>Consider reducing the level of abstraction by simplifying the class hierarchy.</p>
</recommendation>
