        @brief
            In order to assign attached entities to a ShipPart, a ShipPart with the same name as the corresponding entity needs to be created in the <parts> tag.
            Here is a (primitive) example of a ModularSpaceShip with ShipParts and PartDestructionEvents defined in XML:
            @code
            <ModularSpaceShip
                ...
                >
                    <attached>
                        <StaticEntity name="generator"  . . .  />
                        <StaticEntity name="tail" . . . />
                    </attached>
                    <parts>
                        <ShipPart name="generator" . . . >
                            <destructionevents>
                                <PartDestructionEvent targetType="ship" targetParam="boostpowerrate" operation="-" value="0.5" message="Your boost-regeneration is reduced!" />
                            </destructionevents>
                        </ShipPart>
                        <ShipPart name="tail" . . . >
                            <destructionevents>
                                <PartDestructionEvent ... />
                            </destructionevents>
