        (Normally having previously passed in the configspec when the ConfigObj
        was created - you can dynamically assign a dictionary of checks to the
        ``configspec`` attribute of a section though).
        
        It returns ``True`` if everything passes, or a dictionary of
        pass/fails (True/False). If every member of a subsection passes, it
        will just have the value ``True``. (It also returns ``False`` if all
        members fail).
        
        In addition, it converts the values from strings to their native
        types if their checks pass (and ``stringify`` is set).
        
        If ``preserve_errors`` is ``True`` (``False`` is default) then instead
        of a marking a fail with a ``False``, it will preserve the actual
        exception object. This can contain info about the reason for failure.
        For example the ``VdtValueTooSmallError`` indicates that the value
        supplied was too small. If a value (or section) is missing it will
        still be marked as ``False``.
        
        You must have the validate module to use ``preserve_errors=True``.
        
        You can then use the ``flatten_errors`` function to turn your nested
        results dictionary into a flattened list of failures - useful for
        displaying meaningful error messages.
