        * The render templates arrays contains one or more name render templates to be used within the page elements identified the the
        * renderPath. The renderPath is the key of the subelements whereas the value is the name render template.
+       *
        * The render paths used for a cdm_dataportal page can be visualized by supplying the HTTP query parameter RENDER_PATH=1.
+       *
        * It will be tried to find  the best matching default RenderTemplate by stripping the dot separated render path
        * element by element. If no matching template is found the DEFAULT will be used:
+       *
        * - related_taxon.heterotypicSynonymyGroup.taxon_page_synonymy
        * - related_taxon.heterotypicSynonymyGroup.taxon_page_synonymy
        * - related_taxon.heterotypicSynonymyGroup.taxon_page_synonymy
+       *
        * A single render template can be used for multiple render paths. In this case the according key of the render templates
        * array element should be the list of these render paths concatenated by ONLY a comma character without any whitespace.
+       *
        * A render template is an associative array. The keys of this array are referring to the keys as defined in the part
        * definitions array.
        * @see get_partDefinition($taxonNameType) for more information
+       *
        * The value of the render template element must be set to TRUE in order to let this part being rendered.
        * The namePart, nameAuthorPart and referencePart can also hold an associative array with a single
        * element: array('#uri' => TRUE). The value of the #uri element will be replaced by the according
        * links if the parameters $nameLink or $refenceLink are set.
+       *
        * @param string $render_path
        *   The render path can consist of multiple dot separated elements
        *   @see RenderHints::getRenderPath()

        * The part definitions define the specific parts of which a rendered taxon name plus additional information will consist.
+       *
        * A full taxon name plus additional information can consist of the following elements:
+       *
        *   - name: the taxon name inclugin rank nbut without author
        *   - authorTeam:  The authors of a reference, also used in taxon names
        *   - authors:  The authors of a reference, also used in taxon names
        *   - reference: the nomenclatural reference,
        *   - microreference:  Volume, page number etc.
        *   - status:  The nomenclatural status of a name
        *   - description: name descriptions like protologues etc ...
+       *
        * These elements are combined in the part definitions array to from the specific parts to be rendered.
        * Usually the following parts are formed:
+       *
        * The name "Lapsana communis L., Sp. Pl.: 811. 1753" shall be an example here:
        *  - namePart: the name and rank (in example: "Lapsana communis")
        *  - authorshipPart: the author (in example: "L.")
        *  - nameAuthorPart: the combination of name and author part (in example: "Lapsana communis L.").
        *     This is useful for zoological names where the authorshipPart belongs to the name and both should
        *     be combined when a link to the taxon is rendered.
        *  - referencePart: the nomencaltural reference (in example: "Sp. Pl. 1753")
        *  - microreferencePart: usually the page number (in example ": 811.")
        *  - statusPart: the nomenclatorical status
        *  - descriptionPart:
+       *
        * Each set of parts is dedicated to render a specific TaxonName type, the type names are used as keys for the
        * specific parts part definitions:
+       *
        *  - BotanicalName
        *  - ZoologicalName
        *  - #DEFAULT:  covers ViralNames and general NonViralNames
