363 363  There are also a number of SDMX data types which do not have these direct correspondences, often because they are composite representations or restrictions of a broader data type. These are detailed in Section 6 of the standards.
364 364  
365 365  The Representation is composed of Facets, each of which conveys characteristic information related to the definition of a value domain. Often a set of Facets are needed to convey the required semantic. For example, a sequence is defined by a minimum of two Facets: one to define the start value, and one to define the interval.

378 -|(% style="width:107px" %)minValue|(% style="width:872px" %)The minValue facet is used for inclusive and exclusive ranges, indicating what the lower bound of the range is. If this is used with an inclusive range, a valid value will be greater than or equal to the value specified here. If the inclusive and exclusive data type is not specified (e.g., this facet is used with an integer data type), the value is assumed to be inclusive.
379 -|(% style="width:107px" %)maxValue|(% style="width:872px" %)The maxValue facet is used for inclusive and exclusive ranges, indicating what the upper bound of the range is.
