 * Provides the name render template to be used within the page elements identified the the $renderPath.
36
 *
37
 * The render templates arrays contains one or more name render templates to be used within the page elements identified the the
38
 * renderPath. The renderPath is the key of the subelements whereas the value is the name render template.
39
 *
40
 * The render paths used for a cdm_dataportal page can be visualized by supplying the HTTP query parameter RENDER_PATH=1.
41
 *
42
 * It will be tried to find  the best matching default RenderTemplate by stripping the dot separated render path
43
 * element by element. If no matching template is found the DEFAULT will be used:
44
 *
45
 * - related_taxon.heterotypicSynonymyGroup.taxon_page_synonymy
46
 * - related_taxon.heterotypicSynonymyGroup.taxon_page_synonymy
47
 * - related_taxon.heterotypicSynonymyGroup.taxon_page_synonymy
48
 *
49
 * A single render template can be used for multiple render paths. In this case the according key of the render templates
50
 * array element should be the list of these render paths concatenated by ONLY a comma character without any whitespace.
51
 *
52
 * A render template is an associative array. The keys of this array are referring to the keys as defined in the part
53
 * definitions array.
54
 * @see get_partDefinition($taxonNameType) for more information
55
 *
56
 * The value of the render template element must be set to TRUE in order to let this part being rendered.
57
 * The namePart, nameAuthorPart and referencePart can also hold an associative array with a single
58
 * element: array('#uri' => TRUE). The value of the #uri element will be replaced by the according
59
 * links if the parameters $nameLink or $refenceLink are set.
60
 *
61
 * @param string $render_path
62
 *   The render path can consist of multiple dot separated elements
63
 *   @see RenderHints::getRenderPath()
64
 * @param string $nameLink
65
 *   The link path ot URL to be used for name parts if a link is forseen in the template
66
 *   matching the given $renderPath.
67
 * @param string $referenceLink
68
 *   The link path ot URL to be used for nomenclatural reference parts if a link is forseen
69
 *   in the template matching the given $renderPath.

 * The part definitions define the specific parts of which a rendered taxon name plus additional information will consist.
162
 *
163
 * A full taxon name plus additional information can consist of the following elements:
164
 *
165
 *   - name: the taxon name inclugin rank nbut without author
166
 *   - authorTeam:  The authors of a reference, also used in taxon names
167
 *   - authors:  The authors of a reference, also used in taxon names
168
 *   - reference: the nomenclatural reference,
169
 *   - microreference:  Volume, page number etc.
170
 *   - status:  The nomenclatural status of a name
171
 *   - description: name descriptions like protologues etc ...
172
 *
173
 * These elements are combined in the part definitions array to from the specific parts to be rendered.
174
 * Usually the following parts are formed:
175
 *
176
 * The name "Lapsana communis L., Sp. Pl.: 811. 1753" shall be an example here:
177
 *  - namePart: the name and rank (in example: "Lapsana communis")
178
 *  - authorshipPart: the author (in example: "L.")
179
 *  - nameAuthorPart: the combination of name and author part (in example: "Lapsana communis L.").
180
 *     This is useful for zoological names where the authorshipPart belongs to the name and both should
181
 *     be combined when a link to the taxon is rendered.
182
 *  - referencePart: the nomencaltural reference (in example: "Sp. Pl. 1753")
183
 *  - microreferencePart: usually the page number (in example ": 811.")
184
 *  - statusPart: the nomenclatorical status
185
 *  - descriptionPart:
186
 *
187
 * Each set of parts is dedicated to render a specific TaxonName type, the type names are used as keys for the
188
 * specific parts part definitions:
189
 *
190
 *  - BotanicalName
191
 *  - ZoologicalName
192
 *  - #DEFAULT:  covers ViralNames and general NonViralNames
193
