Setting the Description and DetailedDescription attributes of MATLAB classes

Built-in MATLAB classes have values for a Description and DetailedDescription attribute:

>> ?handle
ans = 
  meta.class handle
  Package: meta

    Properties:
                       Name: 'handle'
                Description: 'Base class for handle classes'
        DetailedDescription: ''
  [snip]

Similarly, some methods and properties of built-in classes have the same attributes:

>> a = ?containers.Map;
>> a.PropertyList(1)
ans = 
  meta.property handle
  Package: meta

    Properties:
                     Name: 'Count'
              Description: 'Number of pairs in the collection'
      DetailedDescription: ''
  [snip]

How can I set these attributes for my classes/methods/properties?

It looks like the Description and DetailedDescription properties are not being used yet.

Well, yes I know the documentation says that - except they are being used, as shown in the examples above. You may be right, in that there may be no way currently for a user to set them, but MATLAB itself is setting them somehow. I'm wondering whether it's possible for a user to do that, even in an undocumented way.
