								-- Definition -- 
								Identifier defining the scheme used to assign the identifier.
								 
								-- Description -- 
								Note 1: Reporting requirements for different environmental legislation mandate that each spatial object is assigned an identifier conforming to specific lexical rules.
								Note 2: These rules are often inconsistent so a spatial object may be assigned multiple identifiers which are used for object referencing to link information to the spatial object.

								-- WISE GIS Guidance --

								The element must be reported if the thematicIdIdentifier is reported.
								Data Providers reporting under WFD must use the default value 'euSurfaceWaterBodyCode'.

								-- Definition -- 
								A hydrographic thematic identifier. An identifier that is used to identify a hydrographic object in the real world. It provides a 'key' for implicitly associating different representations of the object. A local identifier, assigned by some authority.
								
								-- Description -- 
								NOTE 1 The identifier may be a national hydrological identification code.
								
								-- WISE GIS Guidance -- 
								Note that the hydrographic identifier is not the inspireId, but a generic hydrographic identifier. The INSPIRE Data Specification on Hydrography (INSPIRE_DataSpecification_HY_v3.1) proposes a "hydrographic thematic identifier" named hydroId (which is composed of localId, namespace and classificationScheme). 
								For WISE reporting purposes, it is recommended that hydroIdLocalId be a unique thematic identifier in the scope of the corresponding namespace.

								-- Definition --

								-- WISE GIS Guidance -- 
								For WISE reporting purposes, it is recommended that hydroIdNamespace be treated similarly to the thematicIdIdentifierScheme in the remaining themes (i.e. identifying the national or international identifier scheme from which the hydrographic identifier was obtained).
