Retrieving annotation/documentation of elements/attributes/attribute-groups

[Ward]

Hello,

I'm working with XMLBeans for some weeks now, but now I'm interested in
accessing the documentation availlable in my xsd-scheme.
Until now I only managed to get the documentation directly under any
complextype, but not the documentation specific to any element, attribute or
attributegroup

Consider following snippet from my scheme:

    <complexType name="titleType">
        <annotation>
            <documentation><!-- THIS DOCUMENTATION I CAN ACCESS -->
 The name given to a resource e.g. a media item, media object, sequence.
                For a series – use the series title; for a programme – a
programme title; for an
                item – an item title. etc. To differentiate between a series
title and programme
                title when these are identical, recommended best practice is
to use a date along
                with the programme title. For example, “News” is a series
title; “News 2007.11.12”
                is a programme title. Titles are recorded as they appear.
</documentation>
        </annotation>
        <sequence>
            <element ref="dc:title">
                <annotation>
                    <documentation>
<!--HOW CAN I ACCESS THIS DOCUMENTATION??? -->
The EBU core metadata set is built as a refinement of the Dublin
                        Core. </documentation>
                </annotation>
            </element>
        </sequence>
        <attributeGroup ref="ebucore:typeGroup">
            <annotation>
                <documentation>
<!--HOW CAN I ACCESS THIS DOCUMENTATION??? -->
The typeGroup is used to define the type of Title such as Episode,
                    Programme, Collection, Programme Group, Series, Item,
Scene, Shot, Element,
                    Segment, Project, , Series Number, Episode Number, Scene
Number, Take Number
                    Recording, Album, etc. The name of the type can be
provided in the form of a
                    text label, or a link to a code of a classification
scheme, optionally
                    accompanied by a definition</documentation>
            </annotation>
        </attributeGroup>
        <attribute name="note" type="string">
            <annotation>
                <documentation> Optional addditional contextual information.
<!--HOW CAN I ACCESS THIS DOCUMENTATION??? --> </documentation>
            </annotation>
        </attribute>
    </complexType>

Any ideas on this?

Thanks in advance
