    Generate config pages from a list of Descriptors into a section.

    <st:attribute name="title">
      Human readable title of the section to be rendered in HTML.
    </st:attribute>
    <st:attribute name="descriptors" use="required">
      hudson.model.Descriptor collection whose configuration page is rendered.
    </st:attribute>
    <st:attribute name="instances">
      Map&lt;Descriptor,Describable> that defines current instances of those descriptors.
      These are used to fill initial values. Other classes that define the get(Descriptor)
      method works fine, too, such as DescribableList.
    </st:attribute>
    <st:attribute name="field">
      Either @field or @instances are required (or @field needs to be inherited from the ancestor &lt;entry> elemetn.
      If field is specified, instances are assumed to be instance[field].

      When this attribute is specified, JSON structure is properly set up so that the databinding
      can set the field (or pass this collection as a constructor parameter of the same name.

      This is more modern way of doing databinding, and thus preferred approach.
