+ The _aq_dynamic functionality allows an object to dynamically provide an
+ attribute.
+
+ If an object doesn't have an attribute, Acquisition checks to see if the
+ object has a _aq_dynamic method, which is then called. It is functionally
+ equivalent to __getattr__, but _aq_dynamic is called with 'self' as the
+ acquisition wrapped object where as __getattr__ is called with self as the
+ unwrapped object.
+
+ Let's see how this works. In the examples below, the A class defines
+ '_aq_dynamic', but returns 'None' for all attempts, which means that no new
+ attributes should be generated dynamically. It also doesn't define 'color'
+ attribute, even though it uses it in the 'hi' method.
+
+ >>> A().hi()
+ Traceback (most recent call last):
+ ...
+ AttributeError: color
+
+ The class B, on the other hand, generates all attributes dynamically,
+ except if it is called 'bonjour'.
+
+ First we need to check that, even if an object provides '_aq_dynamic',
+ "regular" Aquisition attribute access should still work:
+
+ >>> b=B()
+ >>> b.a=A()
+ >>> b.a.hi()
+ A('a') red
+ >>> b.a.color='green'
+ >>> b.a.hi()
+ A('a') green
+
+ Now, let's see some dynamically generated action. B does not define a
+ 'salut' method, but remember that it dynamically generates a method for
+ every attribute access:
+
+ >>> b.a.salut()
+ B('b').salut
+ chain: B('b')
+
+ >>> a=A('a1')
+ >>> a.b=B('b1')
+ >>> a.b.salut()
+ B('b1').salut
+ chain: B('b1') <- A('a1')
+
+ >>> b.a.bonjour()
+ Traceback (most recent call last):
+ ...
+ AttributeError: bonjour
+
+ >>> a.b.bonjour()
+ Traceback (most recent call last):
+ ...
+ AttributeError: bonjour
+
